A new Marine Captain was assigned to an outfit in a remote post in the African desert. During his first inspection of the outfit, he noticed a camel hitched up behind the mess tent. He asked the Sergeant why the camel was kept there. The nervous sergeant said, "Well sir, as you know, there are 250 men here on the post and no women. And sir, sometimes the men have "urges". That's why we have the Molly The Camel." The Captain says, "I can't say that I condone that behavior, but I do understand about "urges", so the camel can stay."
About a month later, the Captain starts having his own "urges". Crazy with passion, he asks the Sergeant to bring the camel to his tent. Putting a ladder behind the camel, the Captain stands on the ladder, pulls his pants down and proceeds to have sex with the camel. When he finishes, he turns to the Sergeant and asks "Is that how the men do it?"
No, not exactly, sir... "They usually just ride the camel into town where the girls are".
