Funny enough, first time I was in Berlin, I was meeting with a friend and one evening we went to a random currywurst stand to grab some food. There was no one else around and the guy came out to talk to us. I generally avoid interacting with people so the guy started talking to my friend(who is the complete opposite) and when my friend told him he was French, the guy entered some strange mode and began a lecture on French potatoes, and 10 minutes later he asked if I was French too. I said I was from Bulgaria, at which point the guy gave an even longer lecture on Bulgarian potatoes, incluing regions, villages and whatnot. I guess by the time he finished I had my wtf face on and he paused for a few seconds and said "Haha, I'm the potato master, I know everything about potatoes".
