One of the funniest anti-scammer sites i've seen so far.

http://www.ebolamonkeyman.com/

Thats a great site, playing with those 419 scammers can be a really seriously time consuming hobby. As monkey man says (and I couldn't have put it better myself)

1. Never believe anything these idiots say.
2. Never feel sorry for them. They have caused a lot of suffering for many people.

Anyone, who's ever got one of those emails should also checkout www.419eater.com where someone will be willing to bait them, if you don't have the time yourself.
