Ahmed the Arab came to London from the Middle East , and he was only here a few months when he became very ill. He went to doctor after doctor, but none of them could help him.
Finally, he went to an Arab doctor who said, "Take dees bocket, go into de udder room, shit in de bocket, piss on de shit, and den put your head down over de bocket and breathe in de fumes for ten minutes."
Ahmed took the bucket, went into the other room, shat in the bucket, pissed on the shit, bent over and breathed in the fumes for ten minutes.
Coming back to the doctor he said, "It worked. I feel terrific! What was wrong with me?"
The doctor said, "You were homesick."
