Do you have any geeky T-shirts?

If so, which ones? I know a guy at my school who’s a total nerd and he’s not afraid to show it. I love his nerdy yet witty collection of T-shirts. I don’t have anything like that; the closest I have is a Google T-shirt that says “Google” on the front and “I’m feeling lucky” on the back (This one here: http://techzest.files.wordpress.com/2008/04/google-tshirt.jpg). Anyway, I just saw a T-shirt that I really want:
