This design is perfect for The Big Bang Theory geeks. During a conversation about football, Sheldon asks Leonard, "are you making this a tier one friendship request?"

Sheldon, raised in Texas on every incarnation of football except European, is approached by his friend Leonard to teach him all about the sport to impress Penny and her family at a football party. Hilarity ensues.

This shirt is sure to bring the laughs for the Big Bang enthusiast in your nerd herd!

Released in 1981 as a sequel to Galaxian, this shooter is simple and addictive. For thirty years the series has enjoyed longevity, having its most recent installment, Galaga Legions, released in 2008 for the Xbox Live Arcade. Both old-school gamers and new players alike will appreciate this simple design.

Conversations about video games and all of the attendant technological advances are sure to be engaging. After all, who really wants to talk about the weather or the latest reality show drama? Call out to the other gamer geeks with this fun, nostalgic design.

If there has ever been a smart guy who knew he was smart on TV, it would be Sheldon. Sheldon Cooper is part of the CBS show "The Big Bang Theory," where he acts as a sarcastic physicist that has become the defining role for the show. He's got an IQ of 187, even though he says that his mind actually exceeds the limits of normal testing. Now he has been immortalized as The Flash, a character he once dressed like on the show.

The T-shirt itself is actually a parody to David Bowie's Aladdin Sane album cover. That cover features Bowie with a similar headshot and a rainbow lightning bolt on his face. Sheldon could never be Bowie though as he has immense stage fright. His Bowie-isms are better left to red T-shirts. If you've been looking for a way to get this obsessive, egotistical, panic driven comedic genius in your wardrobe, this T-shirt is the perfect solution. Be careful though. Wearing it may make you social awkward without reason.

This design of the superhero The Flash, worn by Sheldon on The Big Bang Theory, is perfect for anyone wishing to attract other fans of the cerebral comedy. Winner of the 2011 Golden Globe for Best Performance in a Television Series (comedy or musical), the series is a cult favorite to physics majors everywhere.

Compare notes and see who can spot the most former cast members of Roseanne, or draw up some convoluted algorithms of your own. No matter what Big Bang-related fun enthusiasts of the show get involved in, show your support with Sheldon-wear! Of course, the plaid pants are optional.

Forget Ryan Reynolds, Sheldon wears one!

Winner of the 2010 Primetime Emmy for Outstanding Lead Actor In A Comedy Series, Big Bang Theory has nerds everywhere cheering for the underdog. In 2011, the program was so popular that contracts were signed for an additional three years, practically guaranteeing fans their weekly fix through the end of the 2013-2014 season.

Sheldon has an IQ of 187 and possesses two PhDs. Too bad that he is completely anal in his commitment to routine and his complete lack of a sense of humor. This facet of his personality leads to hilarious results when dealing with his room mate Leonard, another CalTech genius, with whom he shares a quirky walk-up apartment across the hall from Darlene... er, Leslie. Yeah, Leslie.

The show is so popular that it was stolen, nearly line for line, on a Belarus government television station! This Green Lantern shirt is the same design that Sheldon wears on the show. Known for his intense intelligence and acerbic wit, Sheldon is simply 'the man' of the physics world, despite his dubious fashion tastes. Buy one for yourself, or give it as a gift to upgrade to a Tier One friendship!

When you're hangin' with your homeslices, coding that sweet new module or blasting n00bs on CoD, wearing the most pimp nerd gear is sure to raise your street cred. This design features the Atari gaming system, which is immediately recognizable to all the other O.G.s (Original Gamers) out there.

Whether it's a WoW marathon or stylin' at the ComiCon, keep it real with this old-skool tee. The honeys will also dig it, as long as you can restrain yourself from making joystick references. Who needs 3D gaming? Word.

Though the technology used to build this masterpiece of fighter engineering may have been stolen from the Goa'uld (who no doubt stole it from someone else), the F-302 fighter-interceptor is all Earth when it comes to style and grace, and so is this specifications poster.

Using the original CGI graphics construct from the three Stargate series, fans get a view of the F-302 - top and bottom, front and back - along with a little bit of information detailing the weapons systems and other important capabilities of the ship. It's easy to see after a little inspection what makes these ships so effective both within the atmosphere and in the depths of space. The F-302 fighter-interceptor is a crucial asset to the Tau'ri fleet and has proven itself time-and-again in the defense of Earth and its people.

Supporters of Stargate can show their loyalty to Earth by displaying one of these posters proudly on their walls. Supposedly, knowing the specs of the F-302 is also a great way to impress the ladies, or at least the more combative ones.

It was only a matter of time before the Doctor decided that he needed to leave a record in the time stream that represented the truth of the man behind the myth. Or, perhaps more appropriately, the body of the man beneath the clothes.

This print comes from a painting that appeared briefly at the beginning of Doctor Who, season 6, in "The Impossible Astronaut" episode. It was created by a girl by the name of Matilda, the daughter of a nobleman and a woman with whom The Doctor may have gotten a little too friendly. Luckily, the girl's father was so busy chasing the Doctor that he completely forgot about the painting. This masterpiece of Whovian art has since been shipped through time to be reproduced and sold via the internet.

The ladies will love Doctor Matt "Sexy-Sexy" Smith, standing tall and bare, trident in hand, looking a bit like an angel or a Greek god. This satin-finish poster will look perfectly at home sitting on the wall of any loyal Doctor Who fan.

Fish sticks and custard not included.

With her short skirts and flirtatiously kissable attitude, you'll want the Amy Pond pose-able action figure from the current incarnation of the Dr. Who series. The action model of Amy is wearing one of her leg baring short skirts with her trademark curly red locks flowing down her back.

Despite her realism, remember she's just an action figure. However, your Doctor Who collectible figurine might have fun adventuring with Amy and may even want to share her plastic display case. However, another use for your new Amy Pond keepsake is to give her as a gift to your son or daughter who is also a fan of the Dr. Who franchise since you've introduced him or her to the show at a young age.

The character of Amy Pond is portrayed by actress Karen Gillan. Amy is the doctor's companion, and she first met him when she was seven years old. The doctor crashed into Amy's backyard one evening, and she asked him to explore an unusual crack in her wall that consumed her parents.

The Doctor agreed to help her, but an interruption caused him to leave, and he told Amy that he would be back within five minutes. Unfortunately, the five minutes turned into twelve years causing Amy's aunt to believe she was mentally disturbed. After the doctor returns, he and Amy have many adventures together.

Now, you can be reminded daily of Amy's exploits with the brilliant, world saving doctor. Furthermore, no Doctor Who collection would be complete without Amy Pond.

Let nostalgia reign with your new Deanna Troi action figure. As an integral crew member of the Starship Enterprise, Deanna uses her mind powers to help Captain Picard and the rest of her team out of dangerous situations. Unfortunately, Deanna's unique abilities often put her in harm's way.

The character of Deanna Troi first appeared on Star Trek: The Next Generation. She accepted the career assignment of the ship's counselor where her extrasensory abilities came in handy. With a poseable action figure in her likeness, you can bring the memories of the classic Star Trek series back to life.

During the course of her employment on the Enterprise, Deanna faced many obstacles. For example, an alien spirit hijacked her body, she was kidnapped and changed into a Romulan Major and experienced numerous romantic encounters. However, she finally married Captain Picard's number one lieutenant, Starfleet officer William Thomas Riker, during a traditional wedding on Earth.

By possessing your very own Deanna action figure, you can recreate classic scenes from the popular series, spin-offs and movies. Furthermore, a highly detailed Deanna model will surely add value to your already personally priceless collection of Star Trek memorabilia.

As an über fan of all things Star Trek, owning a realistic phaser from The Next Generation will surely bring your collection to completion. With sound effects from the show, you may need several phasers in your home for every member of your family.

The futuristic Star Trek weapon made its first appearance during the original series. However, when you purchase this replica, you'll have the defense device most often used in the follow-up series The Next Generation.

You will need your considerable imagination to create the bright orange laser beam that the phaser emits during an attack. On the bright side, the laser coming from your phaser could be the color of your choice.

This classic phaser would make the perfect gift for the Next Generation fan in your life, and you'll receive plenty of credit for your gift giving originality. Furthermore, with more people in your group owning phasers, the better your reenactments will become.

Got Time?

Dimensional transcendentalism is complicated concept, but it certainly seems to be a marketing ploy on the Doctor Who Got Time shirt. The distressed graphic design is made up to look like it was an actual advertisement. The TARDIS stands out against a background that could have come straight out of the modern British golden era. A quaint English dairy might just as easily have used this type of advertisement seventy years ago.

This shirt has the officially licensed Doctor Who logo inside of the collar. That's pretty good consider that one doesn't want the Celestial Intervention Agency going after their hide. Various spin-off media in connection with the Doctor Who series has suggested that organization is rather clandestine to say the least. The Time Lords have a dark side, but they don't often show it.

The neutral colors might make some individuals do a double take. It really doesn't look like a science fiction themed shirt. That's why it works so well. Many non-fans might not even recognize what the TARDIS is. They might end up believing that it is a classic successful brand. That's actually quite true in many ways. Doctor Who has been very successful for the BBC. While that doesn't mean that fans that wear this shirt can be called sellouts, it does mean that they'll be supporting the continued success of floppy hats and long scarves.

The Dalek Will Protect Your Money

The Dalek Money Bank might be seen as a safe investment. Many people have lost faith in their accounts with the current state of the world's financial institutions. Stories about debt have filled the front pages of newspapers and websites on both sides of the pond. Banks have had to deal with closures and new legislation in the wake of unspeakable crisis. Therefore, it makes sense to put one's money into a blue guardian that is sure to obey.

While it might not exterminate every money problem, this bank is sure to provide plenty of room for pocket change. It naturally accepts change in the form of coins or pence. The shell is done up to match the newer incarnation of the Doctor's adventures. However, diehard fans might very well associate this bank with the Peter Cushing movies. Young fans might not remember the pair of films, but that doesn't mean that colored Daleks are actually something new. For that matter, the TARDIS is considerably older than most people realize.

Fans that grab this bank might not exactly care for the TARDIS. In fact, it might make a perfect gift for anyone that roots on the bad guys. The Daleks have so far failed to exterminate the Doctor, but that doesn't stop some people from dreaming. Banks are often used to teach young financiers the value of money. One might want to save money for an alien invasion in this case. One will need to bribe their alien overlords in the future.

Anyone that wants to enjoy high tea with some real class needs to pick up the TARDIS mug. Some fans might want to take to calling it a TARDIS beaker instead of a mug. After all, Doctor Who is a rather English series and speaking the part could be every bit as important as living it to a cosplayer. The blue police call box has been reproduced in all its glory in this miniature ceramic offering.

The mug is square like the original, even though most containers are circular shaped. Apparently dimensional transcendentalism doesn't allow one to change shape very easily. That could also have something to do with the fact that the Doctor's chameleon circuit hasn't worked properly for years. If it had, it wouldn't still be stuck in the form of a blue police call box.

Therefore, any maintenance done on the TARDIS would actually be detrimental to the Doctor's success. Well, it would be a determent to the success of the BBC anyways. Either way, one should just learn to drink out of a mug with straight sides.

This Dalek Poster is perfect for fans who want a great way to show their alliance to a winning team. The Dalek nation grows each time another cyborg is assembled in the shape of a strange trashcan. The five Daleks on this officially licensed poster are positioned above the Doctor Who logo. They are also positioned above the BBC logo. Perhaps this suggests just how superior they are to mere humans. Fragile organic bodies are weak, but pure machines lack independent thought. The Daleks have attempted to combine both aspects into one living machine.

Then again, there isn't much independent thinking going on among a race that simply obeys whatever command they are issued. Two yellow Daleks seem to be taking orders from a classic silver Dalek. A red unit and a blue one aren't too far off either. One can probably easily imagine that the silver Dalek is comfortably in the driver's seat. Seniority is a strong force, and apparently this is even so in a world of machinery. One has to wonder what sort of upgrades a Dalek needs to receive to stay current.

It almost seems as though this small crew is materializing in front of a planetary body out of some type of mist. Perhaps the planet in question is Earth. This poster might be a good thing to have if one wants to be able to survive the coming assault.

Witness the evolution of Starfleet technology with this Star Trek USS Enterprise NCC-1701-D poster. The poster displays a smaller inset diagram of the previous craft to teach fans just how much the United Federation of Planets changed ship designs between the 23rd and the 24th centuries. The original Enterprise was refit and eventually replaced after her demise by the USS Enterprise-A. Next came the Enterprise-B, which was damaged on her maiden voyage. The ill-fated Enterprise-C was one of the few Ambassador class Starships that fans got an opportunity to see. Plenty of fans will rejoice at the fact that the NX-01 seems to be downplayed. No one should have to be the one or two individuals that are displeased by that.

The Galaxy class Enterprise-D was the penultimate in Federation Starship technology. Some fans might vehemently cling to the idea that the Sovereign class could beat out the Galaxy. Most fans agree that the Galaxy class is the most visually attractive class, however. Perhaps it needed to be. This incarnation of the Enterprise had to carry families and a pretty boy commanding officer. The cutaway diagram that takes up most of the poster can give one a bird's eye view of everything that she had to offer. Please don't waste any time looking for the bathroom, though. No one in the 24th century has ever been able to find it either. The inventor of Warp Drive wasn't much of a fan of that fact and he was quite vocal about it.

This Return of the Jedi poster might be able to bring back a few memories of when things were a little simpler and science fiction was just enjoyable. Star Wars has become far too complicated lately. A fan war has broken out that rivals anything that the Rebel Alliance and Galactic Empire ever got involved in. The recent films have caused people to argue about whether or not different events can actually be considered canon. Sometimes, it might be best to take a step back into a peaceful era when the combat was on the screen instead of in the convention halls.

A powerful B Wing races past a pair of TIE Interceptors doing battle with an X Wing and a pair of A Wings on this impressive poster. The unfinished Death Star looms ominously in the background as the scene takes place over the Forest Moon of Endor. This is indeed an auspicious occasion, but an Imperial victory might change things for the worse. It could also be for the better depending on how much stock one has invested in the Kuat Drive Yards.

Daleks are probably in the 1%

The Vote No Daleks shirt is perfect for those science fiction fans that might not be bloodthirsty or obsessed with villains. Many people are concerned about the way that politics has changed the world. There are numerous legislative actions that raise the ire of voters. Extermination is sure to become a major issue in any election year. It doesn't seem that legislative bodies on either side of the pond want to deal with alien invasions. This shirt is an excellent way to show that one cares about a growing threat to international security. That threat comes in the form of fictional trashcan robots.

The shirt demands that individuals go to the polls and stop the extermination menace before its too late. The neutral red color is perfect for this sort of a distressed vintage display. It even makes it look older. Fans of the shirt probably believe that everything should be allowed to age naturally. The Daleks probably wouldn't agree, considering that they intend to wipe out inferior races of beings.
