Has anyone else ever received a chain letter with 6 names that send $1 to?

I received a letter with 6 names on it...in short...you send $1 dollar each name...make 200 copies...take top name off add your name...when u send your money say you want to be added to their mailing list...states that this was shown on Ophra and 20/20 and completely legite because you are selling a svc...and in 2 months time should receive around $170,000/.....hmmmm just wondering if I'm too naive too actually think people do this and make money...any comments? or has anyone ever done this?
