As Seen In: The Collection (2012)

At first, it's the ideal situation: You're dancing and most likely boozed up inside a trendy, crowded nightclub where everyone—girls, boys, whatever—just wants to have fun. It's a Friday night, the music is pumping, and the next round's on someone else.

You're having such a blast that, like the characters in The Collection's opening sequence, you're unable to see the all-black-everything madman hanging out way up in the rafters, the guy who's somehow erected a massive, dance-floor-spanning rake that's about to sweep through the venue and dice everyone in attendance into human kabobs.

Just hope that the last song you'll hear isn't "Gangnam Style."
