Nevertheless, my reply to that sort of scam email would be:

"Hi,

thank you for taking time to send your recent scam mail. Concerning your generous scam offer, I have a counter offer in response to yours to make:

If you send 10,0000,00000 USD to my paypal account at turnoi_scam@yahoo.com within the next three days, I will send you some of my nice big and fat crocodiles to give you scammer folks a big bite. I think you do deserve it!

Have a great day, and refrain from bothering me again.

T. "

Normally, I do not receive any replies when replying occasionally to such scam emails. I rarely do, but sometimes I like to make a bit of fun with them.
