How did I miss this? Apparently there's an intercollegiate quidditch league, with brooms and quaffles and everything.
Obviously, muggles can't fly on their broomsticks like players in Harry Potter's world, so instead they're required to hold a broomstick between their legs at all times. Snitches, instead of golf-ball-sized feathered things, are cardiovascularly-fit cross-country runners wearing all yellow who try to keep both teams' seekers from grabbing a black sock from the waistband of their pants.
So wonderfully geeky! And here for your viewing pleasure, from March, is Greg Gumbel providing the play-by-play of a quidditch match between Princeton (!) and Middlebury.
