An Israeli, a Brit, a Russian, a Vietnamese, and an American are sitting in a restaurant. A reporter comes by and asks, “Excuse me, but can I get your opinion on the recent grain shortage in the third world?”
The Brit asks: “What’s a ‘shortage’?”
The Vietnamese asks: “What’s ‘grain’?”
The Russian asks: “What’s an ‘opinion’?”
The American asks: “What’s the third world?”
The Israeli asks: “What’s ‘excuse me’?”
(As a note, this is not strictly an Israeli joke; the Israeli can be replaced by other stereotypically rude or overbearing people—for example, New Yorkers—or those used to being treated as second-rate citizens, with little effect on the joke.)
