1 - You and some friends find out when there is a local little league baseball game or football game (any outdoor sport).
2 - Don't get drunk (so you don't get arrested for public drunkenness).
3 - Paint your face and get decked out in team colors.
4 - Go to the game and cheer for the team like you were a frat guy at a college game.
5 - Have a non-conspicuous bystander planted in the stands to tape the whole thing.
6 - Running across the outfield mid-game is optional but highly recommended
** you just have to be careful not to do anything illegal **
Price: $3 (for facepaint)
