A World War II Royal Air Force pilot was telling a grade school class about his days in the air corps. "In 1942, the situation was really bad. The German air force was very strong. I remember one day when I was flying my fighter, protecting our bombers, when suddenly out of the clouds these Fokkers appeared." Several schoolchildren giggled. He continued, "I looked up and one was right above me. I pulled up, aimed, and shot down that Fokker. Then they swarmed everywhere! Suddenly I realized that there was another Fokker behind me." By now the students were laughing out loud. Their teacher interrupted. "I think I should explain that 'Fokker' was the name of a German-Dutch aircraft manufacturer." "That's true," said the old pilot, "but these fokkers were flying Messerschmidts!"
