Geeky T shirt slogans

[bailzzararco.livejournal.com]

One of my minor characters is a computer geek, he's fat, but really smart, and basically a nice guy. I have him wearing a shirt with a slogan on it, but I can't think of one. Please help me out. The slogan can also have a picture with it. It will help me flesh out this character and also help with my word count. Thanks!
