Whoopie Cushion - Classic Practical Joke

The whoopie cushion is a classic joke that can be hard to execute as the cushion tends to be a large and conspicuous prop. Here is how it works:

1)The whoopie cushion is a rubber bladder type advice that allows a prankster to blow air into it so it puffs up.

2)Place the inflated cushion on a seat where a victim will sit down.

3)Once the victim sits on the inflated whoopie cushion, the air will be forced out and it will make a loud embarrassing farting sound.

The whoopie cushion was invented in the 1940s.
