Shark Punch (via Sharpshirter)

Ah, the eternal struggle between man and nature continues. That ugly fish gets what's coming to him with on the Shark Punch t-shirt from Sharpshirter. This is what happens to animals who refuse to class things up.

Droidberg (via Redbubble)

A Futurama / Android mash-up t-shirt, why not? Zoidberg meets everyone's favourite mobile OS with the Droidberg tee from Blayde at Redbubble.

Banksy Panda (via Supergoodtees)

Wear everyone's favorite graffiti artist with the Banksy Panda t-shirt from Supergoodtees. I was introduced to Banksy via my favorite Simpsons opening sequence of recent seasons, but I am also loving this action movie star panda street art.

Grapathy (via Topatoco)

Burnt out on Graphjam? Then the Grapathy t-shirt from Topatoco is for you. If I'm reading this graph correctly, the limit of variable y as variable x approaches 0 is go %#*& yourself.

Why So Curious (via Threadless)

I hate posting too many Threadless t-shirts, and I hate posting unobtainable t-shirts, but I can't help but share the Why So Curious? concept design by Andy Hunt. This is the best comic / children's literature mash-up since The Lion, the Witch, and the Watchmen*

*Not a real thing or a good idea.

Big Bots (via Snorg)

Autobots meet Mix-a-lot with the Big Bots t-shirt from Snorg. Whether it be Optimus Prime, Mecha Godzilla, or Daisy Mae 128k, with this t-shirt, you can represent your massive mechanical love.

Harry Stardust (via Made With Awesome)

Glam Rock meets Hogwarts in the Harry Stardust t-shirt by Made With Awesome. I hereby declare this t-shirt design the best combination of David Bowie and film since Labyrinth.

Spiders from Mars, indeed.

Death Rate (via Magu)

Explore the darker side of statistics with the Death Rate t-shirt by Magu Clothing. You'll learn fun facts like being killed by a spider is five times for likely than getting fatally chomped by a shark, all while looking appropriately morbid sporting a big ol' skull on your chest.

Knifey-Spoony (via Powerup Apparel)

Know your cutlery with the Knifey-Spoony t-shirt from Powerup Apparel. This has got to be the best subtle Simpsons reference t-shirt since the Fishbulb.

Dinoboy (via Ignoble)

The 9 to 5, shirt & tie type job might not be extinct yet, but you can help speed it on its way by sporting the subversive Dinoboy t-shirt from Ignoble. You could argue about exactly what type of Dinosaur skull is featured on this design (Or, argue about what is the best dinosaur), but in any case, it's a poignant, slick t-shirt design.

Robot & Triceratops (via Etsy)

Automatons sally-forth in the Robot & Triceratops t-shirt by happyfamily. If Toy Story 3 has rekindled your love of classic toys, this is a t-shirt for you. It seems to be a sold out single printing (being Etsy), but we can cross our fingers in hopes that the design doesn't become extinct.

Shark vs. Bear (via Anonymous Venice)

Not to be confused with other notable mammal / shark meetings, the Shark vs. Bear t-shirt from Anonymous Venice is just awesome (jawesome?) It is a well established fact that bears and sharks are natural enemies in the wild, and this tee celebrates this totally, 100% true fact.

Gundam Calling (via Chop Shop)

This one's been making the rounds in all the usual blogs, but I couldn't pass up posting it. Mix equal parts rock and robot and you get the magnificent Gundam Calling t-shirt from Chop Shop. Easily the best Chop Shop t-shirt that features something other than things made from other things.

Donuts Love Policemen (via Threadless)

Ahh, a convergence of two of my favorite t-shirt themes: monsters & snacks. The Donuts Love Policemen t-shirt over at Threadless may seem familiar to fans of The Simpsons, but it welcomes a more suitably ironic theme. I wonder if the officers featured on this design are of the jelly-filled or the glazed variety?

Creation Becomes Creator (via Teextile)

I hate posting Teextile shirts because they come with an expiry -- this one's being in just under 3 days from this post (or sooner if LEGO's lawyers get wind). You have got to love the vivid colors of Teextile's Creation Becomes Creator t-shirt, featuring everyone's favorite Danish plastic building block toy.

Ninjas vs. Pirates (via Tenbills)

The stories ninjas and pirates being mortal enemies may be true, but the stories of super ninja marksmanship may be exaggerated. If you don't believe me, ask a ninja. The Ninjas vs. Pirates t-shirt from Ten Bills has a lot going for it, but the ninja with the little beard is easily the best part.

Sixpack Todd James General (via Allike)

Get decked out in parade brass with the Sixpack Todd James General t-shirt at Allike. This functional tee is also good for a cheap Sgt. Pepper-esque costume.
