After many days (weeks, month) traveling through the desert on his camel, a guy is so horny he can't stand it anymore.

So he builds a pile of sand behind the camel to get the proper hight, steps on the pile and tries to f--- the camel; but the camel makes a few steps away from him.

Same story a few times, until he sees a great cloud of sand in the horizon; getting closer, a woman chased by many men. Our guy takes his gun and shoots all the men.

"You saved me, I'll do anything for you, just ask" says the woman.

"Ahh ... could you please hold the camel for me?"
