The It's a Living writers I want to say, came over to The Golden Girls for that show's final three seasons. For example, the episode "The Case of the Libertine Belle" (https://goldengirls.fandom.com/wiki/The_Case_of_the_Libertine_Belle) from The Golden Girls awfully similar to the It's a Living episode "Farewell My Sonny" (https://www.imdb.com/title/tt0613046/)? They not only share the same writer and the same basic plot--a murder mystery dinner that starts with the characters playing out a murder with multiple killers, which turns into a "real" murder that one of the regulars is accused of, that then turns out to be fake as well--and several of the same lines.
