A card game if you really just want to be annoying.
Deck of cards and a warped sense of humor
Do you really need rules for this one? OK, here it goes. Take a deck of cards and walk up to someone. You say "Wanna play 52 card pickup?" They are supposed to say "Sure. How do you play?" At which point you throw, flip or launch all 52 cards into the air and onto the floor creating a huge mess. This is your cue to say "Pick'em up".
