If you know anyone in college right now, I'm sure they've made you watch that nasty-ass flick, "2 Girls, 1 Cup." I'm not linking to that madness. You can YouTube that ish.
That video has spawned oodles of videos that highlight people's reactions to the video itself. This video, showing ?uestlove's reaction, is my FAAAAAAAVORITE. Courtesy of Nigga Know.
