This Arab dude goes into an unemployment office, looking for a job. When the lady behind the desk asks if he has any skills, he replies that he's a camel castrator.

"What!?" , she blurts out.

"Camels are livestock in my country, and they sometimes need to be prevented from reproducing to improve the herd.", he answers.

"But just how do you castrate a camel?", she asks.

"Well, you spread their hind legs out, stake them to the ground, and come up behind them with two flat rocks and...", he demonstrates with his hands.

"Ewwww...", she cringes, "doesn't that hurt?"

"Not if you don't get your thumbs caught between the rocks."

Hey! (rimshot!) Believe it or not, my Mom told me that story.
