Missionaries.

A priest and a nun are traveling across the Sahara on a missionary trip when the camel they were traveling on died, falling and crushing their water supply. The priest looks at the young, attractive nun and thinks "If we are to die in the service of our lord, surely he will forgive an old man one indulgence." He looks to the nun,takes of his pants, and tells her, "I have something to show you." "My Goodness!" the young, naive nun exclaims. "What is that?" The priest responds "It's my staff of life. A man puts it inside a woman to bring life into this world." "Staff of life?" she says. "Thank God! Shove that thing up the camels ass and let's get the hell outta here!"
