French sense of humor So me (not a German, but was living in Germany those days) and a colleague (who is French and lives in France too) were "on-site" in Austria visiting a customer. After the work day was over we went to a nearby farmer's market just for a stroll. We saw some lovely and cheap lemons there and I wanted to buy some but didn't have a bag on me. When I mentioned this to my french colleague, he pulled out a big white handkerchief from his pocket and offered that we could bundle up the lemons in it. After thanking him I mentioned that it was awesome that he carried a white handkerchief with him since people rarely do it these days and just use tissues. He was like, "Oh, didn't you know, all french men are required to carry a white handkerchief in their pocket. You never know when the Germans might show up". Took me a second to understand the joke, but then we loled at his self deprecating humor.
