The "Gangnam Style" dance is fabulous. Even as a cultural, inside joke, it's still hard to deny how amazing it is. Even Deadpool gets behind the Gangnam Style dance.
But when zombies with cones for hats take to the dance floor, horrifying, creepy things happen. I think it's the way they're looking at me, with their misaligned pupils and... just... *shiver*
