There appeared a number of chain letters that promised to show a clip or a picture if a recepient forwards it to 5-10 more people. Here's one of these chain letters:

Subject: FWD: SOUTH PARK, do this, its awesome

If you send this to 10 people, you will see a clip of a part of a lost film of south park show. You will laugh your ass off.

It's when Cartmen and Kenny go to a whore house and gets laid. So send this to 10 people and a little screen will pop up and you will wet your pants just try it!
