A man is riding his camel in the desert when suddenly it comes to a dead stop. He gets off and pulls the camel by the lead. It walks just fine but as soon as he gets back on, it won't budge. Luckily there is an oasis a short distance away, so he walks there, and finds the nearest camel service station.

The attendant says, "Bring the camel up onto the platform."

He leads it there. The attendant pushes a button, which raises the camel up. He takes a look from underneath and says, "I think I see the problem."

He pushes another button. Out of the ceiling comes a large, flat metal device, which slowly draws back, and then violently whacks the camel on the rump.

The camel lets out a roar, goes running out of the shop and disappears into the desert.

The man is furious. He screams, "What the hell did you just do? My camel's gone now! How am I ever going to catch up with him?!"

The attendant nonchalantly, says, "Step up onto the platform."
