DMZ. I have a co-worker who spent a few seconds in North Korea. At the DMZ, there's a conference table placed right on the border, and North Koreans sit on the North Korean side of the table, and South Koreans on the South Korean side. He went to the North side when he was there on US Gov't business so he could say he was in North Korea. They didn't seem to mind, unlike US Marines in Australia.

("Here in America, we don't tolerate that kind of crap, SIR!")
