I had a friend from Germany some time back, and we were discussing the subject of how people invariably make fun of the accent of people from countries.
When I brought up Swedes, and did a kind of sing-song "YEE dur YAH dur YAW dur" he laughed and said they did the same in Germany!
I demonstrated how we made fun of German accents: "Ow der schlaussen klitzen der voggel straussen!" in a deep guttural tone!
He laughed, and when he asked if I wanted to hear how Germans make fun of American accents, he said in a loud barking tone: "ARF ARF ARF ARF ARF!"
I nearly fell on the floor!
Years ago, some black comedian related a story about going into a Vietnamese owned Stop and Go. He asked for a pack a Marlboro’s. Guy said “Yes, Saalim.” “No. No. Marlboro” VN said “Yes, Saalim.” Salem is generic in VN for Cigarettes. He said “NO, GD it! Marlboro!!” VN said “Ah yes. Saalim.” Guy said “MARLBORO, Damn you!! I shoulda shot yo’ ass when I had the chance!!” I think he walked out with a pack of Kools.
