Noel Murray over at the A.V. Club offers an interesting analysis about an episode of The Dick Van Dyke Show…the one entitled, "The Return of Happy Spangler." It may or may not have impacted what Murray wrote to note that the big monologue Rob Petrie delivers at the end is a routine that Van Dyke had performed on TV a number of times before that series…and he used it again from time to time after. He did it on that weird 1965 CBS variety special that was a tribute to Stan Laurel after he passed. So the script for "Happy Spangler" was probably written around that routine.
