A young man joins the foreign legion, and is posted deep in the heart of
 Africa, surrounded by desert.
 
 After a few months with no female contact, he visits his commander to explain:
 "I haven't had sex for ages. Can you help me?" "Well," says the commander,
 "You can borrow my camel any time you like." The man declined, not wishing to
 seem that desperate.
 
 Six months past, and the man became incresingly frustrated. He went to the
 commander as before, but got the same reply: "The offer of my camel is still
 there."
 
 A year went by, and the poor man could stand it no longer. He went to the
 commander for one more time, his hands shaking: "It's no use. I haven't had
 sex for a year. I must use your camel." The commander agrees, and the man
 takes the animal around the back of the compound and relieves his
 frustrations.
 
 On returning, the man thanks the commander who says, "Anytime, young man. It's
 much quicker to the local brothel by camel, isn't it?!"
