Jack Benny is one of my favorite comedians, and I think his odd, long-running radio and TV sitcom, with its scheming cast of characters, was the template in some ways for Seinfeld. Sadly the episode tapes of the TV version are in poor condition so the program never became a rerun staple on cable. In this 1964 clip from near the end of the show’s run, the host is joined by Walt Disney, empire builder, urban planner, technologist, Wernher von Braun collaborator and mouse enthusiast.
