White people happen. White people and butts, actually. Last year, Redditor r6bandit left "several disposable cameras" on the hood of his car at Bonnaroo "with a sign asking people passing by to take pictures of themselves." Days later, when he looked through what the unwashed, happy hordes had done with his social experiment, he saw middle fingers, peace signs, duck faces, drunk bros, unfortunate selfies, and a whole lotta (white) butts.
Also, one pair of boobs, but again, mostly butts. Here are some of the more memorable poses. (Warning: a couple may be mildly NSFW due to dude crack.)
