"A priest and a nun in the desert" joke

A priest and a nun were riding a camel through the desert and the camel passed out and died. Since the priest and the nun had no way to travel they knew they were going to die. The priest asked the nun, "Since we are going to die anyway is there anything I can do for you?"

The nun replied, "Well... I've never seen a naked man before." The priest being the kind man that he was took all of his clothes off.

Pointing at the priest's dick, the nun asked, "What is that?"

The priest said,"It is my sternum."

"What does it do?" Asked the nun.

"It brings forth life." said the priest.

Then the nun said, " Well stick that on up in the camel and let's get outta here!"
