bagpipes
There was a Scotsman, American,and a Mexican. They were driving along a road in Canada. They all saw a cow and the Mexican said, “That is a Mexican cow because of the spots.”
“No,no,no!” said the American. “That is an American cow because of the way it walks.”
“No, you are both wrong!” said the Scotsman. “It is a Scottish cow because of the bagpipes underneath.”
