Have you ever played the game 1000 blank white cards?  The game is one in which you don't really have rules.  Or, you make them up as you go.  And then you break them!  And you draw!  And write stuff!  And get points!  Or lose points...   

The way it works is this:  everyone gets dealt a hand from a pile of blank white notecards at the beginning of the game.  They are armed with only a pen and their creative (or vicious) minds to make their own cards.  The cards can give or take points, suggest an action, make up a rule for the game, or are just to make people laugh.  I find that most of the cards fall into this last category.  Once everyone has a few cards with which to start, you simply go around the circle and play your cards, draw from the middle pile, make new cards as you go, and see what transpires.  

Here are a few cards I drew the last time we played.  I apologize for the grossness of the first one.  Groooosss.

When I played, one card made everyone eat bites of hot hot salsa or lose a turn.  One friend got peckish and made a "go get me a snack" card, and one card gave the player points if they could get our dog to bark.
