NO you are not crazy! I've been wondering where the heck that episode was myself. I remember it fairly well.
I have it on one of my VHS tapes somewhere. I believe it was Fox's last episode of the show. I still remember Bebe making a comment about Thurgood's "stubb" being on a rise. Muriel threatened to leave Thurgood if he was the father, and if not she said, "I'll take you back."
I remember Mrs Avery's old partner in crime came back and was tryna kill her, but at the end, when they showed how things were resolved for everyone she was fine because something happened to him (stroke I think). I also remember Thurgood's doctor saying "Oops" when he was told he mixed up his patient's charts. Then they showed Thurgood and Bebe's son in her womb! Looked like Thurgood!
