If you’ve never heard it (or seen his TV show on some classic channel), the Jack Benny Show was groundbreaking in its day. And it still has a basic formula that I assure you WILL work today: he made everyone else the star.
Whether it was his announcer, his wife, a singer, a guest, or any other cast member, Benny was quite willing to take a back seat. He never minded being the butt of a joke, overshadowed by another comedian, or made to look like a fool.
