ANGELS: Father! We are tired of these Nigerians in heaven.
GOD: What have they done this time?

ANGEL: Everything! They don't listen to instructions! They don't obey traffic rules! They don't wait for their turn in anything! They are completely reckless! (Exasperated) In fact they have made heaven a living hell since they got here.
GOD: Then we better send them to hell! (Calls the Devil). Hello..
SATAN: Hello God, call me later. There's an issue I'm trying to resolve.

Ten minutes later:

GOD: Hello Lucifer.
SATAN: I'll call you back. The issue has turned into a crisis.

An hour later:

SATAN: Hello?
GOD: What's going on over there?
SATAN: It's the Nigerians I have with me in hell! (He stammers), they... they... they have quenched the fire in hell and installed air conditioners!
