Anyone tried those pyramid chain letters and you mail $1 or $5 to 5 addresses and it claims you get $$$ back?

I received 2 of those ';pyramid chain letters'; in the mail claiming that if you mail $1 to the 5 addresses enclosed that it works as a chain and then people mail money back to you . I was wondering if anyone has ever tried that and if it worked. Thanks ! not sure what category to put this in either.
