A priest and a nun are crossing the desert on a camel which proceeds to up and die. Sitting there next to the dead camel, out of water in the middle of the desert, the priest says "sister I believe were going to die. Before we do there's something I always wanted to try." He pulls out his penis and the nun, gasping , says "father, what is that?" The priest says "sister this is that which gives life". The nun thinks for a moment and asks "Why don't you stick it in that camel so we can get the hell out of here?"
