A grade school teacher, who was doing a class on World War II heard that the father of one of her students, Helga Jansson, had been a fighter pilot during the war with the RAF. Mr Jansson had having left Sweden in `39 to join the war. She invited him to come in and speak to the class, He was more than happy to talk, and began with a story about a morning patrol where he had been nearly shot down.
    "Ve had been up for about tventy minutes flying over enemy territory, vhen ve noticed, yust in time, dere vas t'ree Fokkers diving on us from above."
    At the first mention of `Fokkers' the class giggled a little bit. The teacher interrupted the story to ask Mr. Jansson to explain to the class that a 'Fokker' was a particular type of plane flown by the German Air Force.
    Jansson replied, "Ya, dat is true, Miss, but dese Fokkers vas Messerschmidts".


(okay, so it was about WWII planes...)
