There is a famous story about musical terminology mistakes attributed to Ralph Sauer, who I believe at the time was the principal trombone at the New York Philharmonic.
He taught a lot of private lessons and was known for a dry sense of humor.
Working with a European student, he asked what crescendo meant in his country. Then he said, "oh, same as in English." (somehow I'm mixing up the order, maybe somebody else can tell this one right) He intended this as a joke, but the student totally lacked a sense of humor and went away convinced Americans were too stupid to know some musical terms were of Italian origin. And spread the story, of course.
