I've been there. We had a new person in the office who didn't believe that such scams could exist, so for the lulz they were assigned to deal with the person. They could say whatever they wanted as long as they didn't agree to pay.

The salesguy ended up screaming at our person who was just playing dumb.

It's also the "Who's Who" scam, where they print your name in a book of important people and sell you the book, or the "You Won A Poetry Content" that Dave Barry had so much fun with. http://www.miamiherald.com/2007/07/22/165002/poetic-license-...
