Mr Deeds Goes To Town (1936)

“About my playing the tuba. Seems like a lot of fuss has been made about that. If a man’s crazy just because he plays the tuba, then somebody’d better look into it, because there are a lot of tuba players running around loose. ‘Course, I don’t see any harm in it.”
— Longfellow Deeds, played by Gary Cooper in Mr. Deeds Goes to Town
