Usually these work well at college parties with the person you have a crush on
  1. Come out of the bathroom with water on your hand, wipe it on someone's face & say "I got pee on my hand"
  2. If someone is casually shooting hoops & misses one, kick them in the nuts from behind. It is a definite crowd pleaser b/c so unexpected
  3. When you are supposed to shake someone's hand say "you don't want to shake my hand b/c it was just down my pants"
  4. I'll remember more later
