Interesting Political-Ethnic Joke

These four guys were walking down the street, a Saudi, a Russian, a North Korean, and a New Yorker.
A reporter comes running up and says, "Excuse me, what is your opinion about the meat shortage?"
The Saudi says, "Excuse me, what's a shortage?"
The Russian says, "Excuse me, what's meat?"
The North Korean says, "Excuse me, what's an opinion?"
The New Yorker, says, "Excuse me? What's excuse me?

I've heard different versions of this joke. Here's the other version:

A Japanese, North Korean and South Korean are at a restaurant.
The waiter approaches and says:  "Excuse me, there's no more meat."
The Japanese looks at the waiter and asks, "What's 'no more'?"
The North Korean asks, "What's meat?"
The South Korean asks, "What's excuse me?"

Of course, this was told to me by a certain Japanese ex-gf who enjoyed such repartee so it's very possible she read the original and tweaked the joke as a shot against the better looking, more industrious, less militant, friendlier, passionate, athletic, talented, South Koreans - right Sayuri-san? ;-)
