72 virgins
An 18-year-old suicide bomber blew himself up and appeared before Allah.
He said, "Oh, Allah, I did your bidding, but I have a request. Since I am only 18 and spent all my time in terrorist training school, I never was with a woman. So, instead of 72 virgins, who also won't know what to do sexually, can I have 72 whores?"
Allah regarded him for a moment, then replied, "Actually, the 72 virgins are here in heaven because butt holes like you murdered them before they could experience the pleasure of sex. So you are here to service them. Since they are virgins, they are quite sexually ravenous; and, frankly, you will be on constant, exhausting duty."
The bomber responded, "Well, I guess I can live with that. How hard can it be to keep 72 women satisfied for all eternity?"
And Allah replied, "Who said they were women?"
