So, you take a lenth of clear PVC line and secure the biggest balloon you can find to it. Put the balloon in front of your belly, run the line between your legs and up your back. Put on the biggest pair of strechy pantyhose/tights you can find to secure everything in place.
now, secure the ohter end of the line to a hand/foot pump. Now take a deck of cards. Each player cuts the deck and what ever number they draw (face cards 10, aces 1) that is the number of pumps they give. the one who pops the balloon/belly looses that round. Reset and play again!
Watch as a Japanese network steals this idea for a game show.
