I have a few favorite episodes. I can't really narrow it down to just one.
But of course the classics are " Job Switching where Lucy and Ethel work at the chocolate factory and Lucy does a commercial where she takes the VitaMetaVegaMin syrup and gets drunk.
But I do think that the episode where Ricky thinks he's going bald is in my top favorites.
