Wanna hear a german one? I hope I can translate it accordingly:
So, there is this soldier. He gets redeployed to a military base in a desert, in the middle of nowhere. On the first day his commanding officer shows him the area. The soldier looks around this desolate place and sees a lot of guys, but he can´t find a single woman. He asks his officer: "How can you live here without women?"
The officer says: "That´s no problem. When we need a woman, we take that camel there." And he points to a lonely camel standing in the sun.
"Really?", the soldier asks. "You take the camel?"
"Sure, why not?"
The soldier shudders and decides that this is not what he wants. So the days and weeks pass in boredom. And finally after a month or so, the soldier can´t stand it anymore. He is in dire need of a woman. So he stacks a few beer crates on top of each other, climbs on them and starts to screw the camel from behind.
After some time the officer comes by and sees that. "What the hell are you doing there?", he asks enraged.
"What?", the soldier says. "You told me, that you take the camel when you are in need of a woman."
"Of course", the officer says,"we take it to ride to the next town."
