Today’s Comic Book Geek Fashion moment should make Batman fans happy. It certainly made me excited enough to buy it, and the time is now—it’s only ten bucks. Sweeeet! But it’s only available at that great price for one week!

This week Threadless is having a one-week Summer Blockbuster sale with t-shirts as low as $10. Included in the discounted batch is this uber cute Batman tee.

The asphalt gray t-shirt is available in both women’s (S-XL) and men’s (S-2XL) sizes as well as kids’ (2-12). As you can see from the design, it shows a rather angry little Bat-tyke running over (more like decapitating …) a stuffed penguin. All Batman fans know that the penguin is an allusion to the adult Batman’s enemy, The Penguin—just another member of his Gallery of Rogues. Still, since this is a toddler Batman (guess some of those billions from the Wayne family inheritance are going straight to child therapy bills), we might just have to assume that either a), Bruce is psychic and knows his future enemies or b), he has a pathological hatred of penguins.

And ladies and gentlemen, say hello to the very first Batpod design … the Bat-tricycle.
