Nice!
Another one of my "self-proclaimed geek" favorites:
The reason I love this shirt so much is because I take it like this: "Yes, I realize I probably look to you like someone who could fix computers and I'm sure you assume that I don't have a social life so I should "have plenty of time to" or "enjoy" fixing your computer; and finally, yes, I probably could fix your computer but NO! I WON'T FIX YOUR COMPUTER A-HOLE!"
...or maybe that's just me :)
