A Jew is travelling in Thailand, and he's been told that very often pork is the meat of choice. He's on a train and man goes by selling bowls of rice and an unidentifiable meat. Wanting to verify that the meat is indeed beef, he asks:"Is it cow?"
"Yes sir!" is the reply, all nodding.
Double checking the man asks: "Moooo?" And again the food vendor replies all nods and positive.
So the man buys a bowl and eats his rice (Thai word: khao) and pork (Thai word: mu). heh heh.
