I've yet to see Napoleon Dynamite...I should though. 
Nerdy T-shirts
I don't own any but would like to. Maybe I'll pick one from these:

Stuff from errorwear.com is pretty cool.
And everyone's seen the famous BSOD tee on Victoria, right? (PG-13 warning)...

My fave shirt, though, (I really do wear it, sometimes even to work, but I've no pic of me in it...) : http://www.teesnthings.com/ProductImages/funny-t-shirts/novelty-t-shirts/large-one-person-t-shirt.jpg
Com'on, those are boring shirts at errorwear!
.
I like to buy those printable iron-on avery labels at staples and print stuff (like old illustrations from the monster manual or fiend folio 
)
i recently found a piece of paper on the ground on which some kid had written 'i will not fight on school grounds' dozens of times. don't know if that qualifies as geek, but the avery label thing surely must.
And you made a shirt from it?
yep...scanned both sides of the punitive assignment paper, printed it on 2 avery labels, and put the front page on the front of the shirt and the back page on the back.
Target has a collection of cool nerdy shirts, including "Vote for Pedro." I bought it, plus an Underdog shirt and a Star Wars shirt. I love being a geek.
i also have a 'Darth Maul' t-shirt. It's nerdy in a BAD way. There's nothing cool about it. I also have a shirt with Malcolm X, Louis Farrakhan, Martin Luther King, Jr., Nelson Mandela, and some other black muslim guy on it that says "It's a Black Thing / You Must Understand". Given that I'm a really pale honky, I get some funny looks while I'm wearing it.

I've always wanted a BSoD t-shirt. Do any of you have one?
Other t-shirts I want:
Pet rocks must be kept on a leash at all times.

Bah, too much work. Besides, I could put it onto a white t-shirt if I get a t-shirt iron-on kit.
Yeah...I should just make my own t-shirts from now on....
