... the only way they can get laid is to find a goat or camel
This general in the Foreign Legion is transferred to a new fort, and half way through his tour of the place, he spots a mangey old camel tied up at the back of the fort.
He turns to the corporal: "What in God's name do you use that for?",he asks.
The corporal replies "Well, sir, there are a lot of men, and now and then, they become, shall we say, horny...."
"Ah, yes, yes, I understand. Fine, move on"
About 6 weeks later, the general wakes up feeling so horny, he'd get up on the crack of dawn and calls the corporal. "Bring me to the camel" says he.
The corporal does, and once at the camel, he makes it stand up, and places a stool behind it. With that, the general stands on the stool, takes out Mr Floppy and inserts it into the camel. He then proceeds to give it the ride of its life. Having finished, he puts away his equipment, and looks proudly at the corporal.
"Well", he says, "is that the way you men do it around here?"
"Er...no, sir", replies the corporal, "We normally just use the camel to ride to the nearest brothel."
