i found this one on another site its well different
First, I took an old wooden tv tray, the kind you use for breakfast in bed, and placed a checker board on it. Then I positioned the board between myself and the erect penis. See where I'm going with this? Me and the penis are playing checkers! I wanted to make him look more like an opponent so I painted some eyes on him and fashioned a crude sombrero out of cardboard and placed it on his head. He almost passed as a swarthy little Mexican dude, staring across the board at me, waiting for me to make my move. We played for awhile and I beat him three games out of four.
