For this game, you need a table with a line of masking tape down the centre of the table dividing the table into two (like a table tennis table without a net).
Ask for two volunteers - one at either end. The volunteers must kneel down and put their hands behind their back.
The object of the game is to blow the table tennis ball past their opponent at the other end of the table. They are allowed to use their chest to block the ball.
The catch is, before starting, each contestant is given a dry cracker to quickly chew before blowing. The end result is cracker crumbs will come flying out of their mouths during the game - very funny :)
