A simple game of skill that looks completely fair, but always leaves the sucker short.
Setup: grab a book of wooden matches and make a "game board" consisting of parallel lines covering a wide surface (make sure each line is exactly one full match-length away from the next). Next, explain you and your mark will take turns dropping matches from approximately 18 inches above the board. They can either aim to (a) HIT the parallel lines or (b) MISS the parallel lines. After a run of 20 matches is complete, the winner's the one who hit their targets the most.
