4. Jack Benny was actually a decent violin player. But for his radio and TV persona, Jack Benny stank. What was the name of his fictional long-suffering violin teacher, played by Mel Blanc?
From Quiz Remembering The Jack Benny Program
Answer:
Professor LeBlanc
Mel Blanc, the voice of Bugs Bunny (and about 1,000 other voices), played various roles on Benny's show, including Professor LeBlanc, who tried - and failed - to teach Benny how to play violin. In one episode, as Benny went through his exercises, the professor kept time by saying,
"Play it softly
Play it smoothly
One-se, two-se
I hates you-se."
