"A priest and a nun" joke

A priest and a nun were traveling through the desert when there camel died
suddenly.
Alone and in the middle of nowhere they decided to sit and wait
for help to come.
During the night they talked about stories of there life
and what they had and hadn't done with their life. It is then that the
preist asks the nun if she has ever had sex the nun replies "no". So the
preist brings up the suggestion that since they are alone and in the middle
of nowhere and could possibly die that perhaps they should try it.
Upon
agreement the Priest flops out his pecker and says to the nun "This is the
staff of life, it brings life to the dead".
In response the nun
replies, "good go screw that dead camel so we can get the hell out of here."
