A suicide bomber died and went to Paradise, as foretold.
When he arrived there he said to Allah that he was ready to claim his 72 virgins, as promised. Out of curiosity he asked Allah why there were so many virgins in heaven.
Allah regarded him for a moment, then replied, "Actually, the 72 virgins are here in heaven because people like you murdered them before they could experience the pleasure of sex. So you're here to service them. And, since they're virgins, they're quite sexually ravenous and, frankly, you'll be on constant, exhausting duty. I shall banish you from Paradise should you fail!”
The bomber responded, "Well, I guess I can live with that. How hard can it be to keep 72 women satisfied for all eternity?”
