Dude, I was on the scholar's bowl and college bowl teams at my schools. (Scholar's bowl being the high school equiv). My best friend made it to the 3rd round of tryouts /w Jeopardy before finally getting cut. What amazes me is that Wheel of Fortune comes on right after Jeopardy, and Wheel must have NO type of screening whatsoever. I mean, they get some of the stupidest contestants I've ever seen. Then there's the Jeopardy crowd, who are some of the most well-read contestants ever.

And as to how some people remember all that crap, There are plenty of people with photographic or audiographic memory. I rarely miss a question in trivial pursuit, since I've heard the answers once. Needless to say, it pisses my mom off to no end.
