Sheldon Coopers 'Super Friends' Shirt

This shirt used to be available at a couple of different places but it's since disappeared from those places (I feel like I'm saying "places" too much... places). I've yet to come up with another exact replica, but for one that looks sorta like it (the biggest flaw is that it's missing the background rainbow) try clicking here. For now, it's the best I can do. Hopefully, I can update it soon.

Sheldon Coopers 'Aquaman Rising' Shirt

Perhaps one of the worlds most scoffed at superheroes, Aquaman actually has plenty of good qualities. Sure, he's not faster than a speeding bullet, he's not a brooding billionaire, he can't move at supersonic speeds, shoot webs from his hands or do most other cool stuff. But he can talk to fish. Who wouldn't want to do that? I know I would. Not to mention, he makes for a pretty snazzy t-shirt. Especially this particular shirt, which you can purchase now from Amazon.com at the link below (clicking the link will open up a new window).
