What you'll need:

• Baby powder
• Eyeliner
• For girls: Ratty, solid color dress
• For boys: Ratty shorts or adult diaper

For the guys out there, this is an especially fun one: you get to walk the party shirtless and show off the toned abs you've honed from sitting in the dark watching movies. And for the girls, at least you'll repel all the drunken frat guys in Joker costumes. (Though we can't help that the two might make for a cute couple.)

Fist, liberally sprinkle baby powder all over yourself. We suggest filling the tub and jumping in for a quick swim. Next, apply heavy eyeliner so that your peepers really jump out from your newly pigmented skin. (Ladies, keep your hair wet and bedraggled; the stringier, the better.) Once at the party, find a good corner or nook underneath the stairs to stare and hiss at people. But do try to show up in the background of every picture taken, slightly out of focus.
