I responded:

 This is splendid. Just give me the MTCN and I'll be sure to toast you with a bottle of fine wine from my new yacht.

Thanks, friend. It's not everyday I get $6.5 million out of the blue.

Hm. You haven't already confirmed the legitimacy of the money? I don't want any of that homosexual terrorist money or money that filthy scammers have touched.

You better get back to me with proof that the money is clean. I'm not going to get raped with a coke bottle in a Nigerian prison because you fucked up and got greedy.

We have to make sure there's no scam here, then we can proceed. Remember, coke bottle. Nigerian prison. Assholes distended. We don't want that.

He immediately tried to reassure me:

 The prrof you need is for your Bank to confirm to you that funds has being wired to your account.Now you need to send the Bank details where you wish to receive this funds because one of your brother's has come foward to claim your funds,which was why i contacted you to verify.

Seems odd I suddenly have a brother in some Darfur pit of hell. But I respond:

Why can't you send me the money via Western Union?

He replied: 

We can only wire your total funds once and not bit by bit.

I was ecstatic. I responded: 

That's even better. Can Western Union handle you wiring me the full $6.5 million at once?
