A Nun and a Preacher were riding camels in the desert, when suddenly both camels dropped dead.

The Preacher turned to the Nun and said, "Since it is evident that we are to die, I have one request. I have never seen a female body... will you show me yours?"

"Certainly", said the Nun, "But I want to see you naked as well."

As they stood there in the hot desert, buck naked, the Nun pointed to his penis and asked the preacher, "What does THAT thing do?"

The preacher knew not what to say, so he told her, "well...it...uhhh...gives life."

"Well, what are you waiting for?!" screams the nun, "Put that in the camel so we can get the hell outta here!"
