My friend told me that one time in Japan he was approached by an older Japanese man who asked him if he could speak Japanese. My friend said yes, and then the man asked if he was an American. He answered yes again. The man then said, "Thank you for occupying my country and bringing freedom and democracy."
At this point in the story, I asked my friend whether he thought the guy was serious, or was just messing with him. He said that he seemed quite sincere. I told him he should have replied, "hey, no problem, come and occupy ours any time."
