Old George Carlin joke:
Here’s a good example of practical humor, but you have to be in the right place. When a local television reporter is doing one of those on-the-street reports at the scene of a news story, usually you’ll see some onlookers in the background of the shot, waving and trying to be seen on television. Go over and stand with them but don’t wave. Just stand perfectly still and, without attracting attention, move your lips, forming the words, “I hope all you stupid fuckin’ lip-readers are watching. Why don’t you just blow me, you goofy deaf bastards.” The TV station will enjoy taking the many phone calls.
