Gain 100lbs in 30 days or your Money Back!

This is just beautiful. It made me really happy - the promotional letter that disguises under funny message... Whoever come up with the idea, - it's just brilliant... BTW: I have to point out that this is not a SPAM. It is a promotional newsletter within special interest group... The message is simply elegant (of course if the context is known - SPAM e-mail on the Internet in 2000-2003...)
