I think I saw that episode of Groucho's show. I seem to recall seeing it rerun a few years ago. (Or maybe it was some clips shown in a Groucho documentary?)

Rip Taylor was never married to Phyllis Diller. She was married twice: first to a man named Sherwood Anderson Diller (5 children), then to an actor named Warde Donovan. I remember they appeared on a few game shows together back in the seventies.
