Email them back and play with them. Those nigerian negroes are dumb as hell. Get them off script, make them think they can get money from you and you can make those dumb negroes do some really funny shit.

I have made them:
*Join my fake church of NAMBLA and hold signs saying they are members of NAMBLA.
* Dress up like KKK members and send me pictures.
* Dick rock string pictures ( One of them pissed of the Church of NAMBLA elders and had to be punished by hanging a big rock from his dick.
* Forced one nigerian male to suck the dick of another nigerian male.
* Made one get a really bad tattoo.
* Working with another guy, we made a nigerian scammer borrow 2600 from nigerian organized crime thinking he was paying for COD shipping of 40 laptop computers. When he opened up the large box, it was an old clothes dryer, when he opened the dryer up, a big cardboard dick popped out. That scammer is most likely dead right now
