An Arab merchant called to a tourist in the market, "Buy a sarong, sir. See, the label says, 'Guaranteed not shrink'." The tourist bought it, but when he washed it the next day, the sarong shrank to half its original size. He took it back and complained to the merchant, "You said it was guaranteed not to shrink."
"The label is written in Arabic," said the merchant, "so you must read it from right to left: "Shrink not guaranteed."
