A classic one. An RAF pilot goes to a primary school to talk about what it was like during the war. At one point he starts talking about one sortie he went out on.
"There was me and my wingman, just flying over the cliffs of Dover, when all of a sudden two Fokkers jumped us and I had to break off."
Theres some snickering as he continues on.
"Fortubately my squadron leader was able to come to our help just as another three Fokkers engaged us."
The snickering continues until the teacher speaks up.
"Children, please. Stop snickering. The Fokker was the name of a German plane."
The pilot looks at her and says: "Yeah but these Fokkers were in Messerschmidts."
