The Sargent replied "Well sir it's a long way from anywhere, and the men have natural sexual urges, so when they do, uh, we have the camel."
The captain said "Well if it's good for moral, then I guess it's all right with me."
After he had been at the fort for about 6 months the captain could not stand it any more so he told his Sargent, "BRING IN THE CAMEL!!!" The sarge shrugged his shoulders and led the camel into the captains quarters.
The captain got a foot stool & proceeded to have vigorous sex with the camel. As he stepped, satisfied, down from the stool, and was buttoning his pants he asked the Sargent, "Is that how the enlisted men do it?"
The Sargent replied, "Well sir, they usually just use the camel to ride into town to find the women.
