Usually when I get chain mails saying they wanna send me 25 million, it's from a male, I respond with this:
I am excited about this! In order for me to validate your identity and credentials, and to conduct business with you, I will immediately need to see nude photographs of your wife in various poses. Please make sure she looks nice in the photos – well groomed, and wearing spike heels, as they really are a turn on for me. Additionally, please be sure if I get a shaved beaver shot (thanks!)...
I am very much looking forward to seeing the photos and doing business with you!
