Hong Kong
When on holiday in Greece, met an American girl at the hotel (I have a knack for talking to American girls at hotels) who couldn't get it into her head that Hong Kong was:
1) In China
2) Belonged to England (this was pre-97 handover)

She kept telling me that no, I was wrong, Hong Kong was in Japan and was owned by the US. Her reasoning behind this? They had McDonald's in Hong Kong.

Dispite the fact that I lived there, and that It was, in fact, possible to take the KCR train (Kowloon Canton Railway) to Mainland China, all of which I explained using small words, she still insisted that I was in error, because only countries owned by the US had McDonald's in them.

I then pointed out that the US didn't "own" any countries. To my utter amazement, she began to spout off a long list of countries that she thought were owned by the US, including Wales, Iceland and Africa.

I could have argued all day, but I went sailing instead.
