It's ironic that I'm posting here, but I heard a guy at Wal-Mart say "I was going to do debate camp, but I can't because I'm doing space camp and band camp."
A real nerd on my school thinks that he is cool, so we followed him after school, we taught that he was dealing coke or something, but actually he was trading "okemon" and "yu-gi-oh" stuff or something! Real nerd!!
I went to math camp once. Not just like some kind of math camp where they teach you how to add stuff, I mean training for the International Mathematics Olympiad.
You need to sit 3/4 hour-long exams, do programs and compete against other kids to get in, cram a bunch of math into your head so you have a shot at going overseas to compete against a bunch of other kids doing these crazy hard math problems! That's pretty nerdy in my books.
I don't know if you'll appreciate this, but I think this is nerdier: writing meta-analytical commentary on geek webcomics.
