Summary Margaret O'Keefe, Cliff's mail carrier girlfriend living in Canada, has come back to Boston wanting to rekindle her relationship with Cliff. Cliff also wants to do so, but he isn't thinking marriage just yet. The biggest hurdle in the relationship is that Ma Clavin and Margaret have never met. When Cliff tells Ma about Margaret, Ma is hurt - she feels like Cliff wants to replace her with another woman. But Ma and Margaret do meet, and after an initial coolness between them, Ma and Margaret get along famously. They get along so well that Ma proposes to Margaret for Cliff and Margaret accepts, without Cliff even being there. Ma and Margaret announce this news to the gang at the bar, but Cliff doesn't yet want to get married. He will have to tell both Margaret and Ma, the latter who may be the more difficult person to tell. In doing so, Cliff and Ma demonstrate who wears the pants in the Clavin household. Meanwhile, Rebecca and Sam are still trying to have a baby. It's been two months without success. Rebecca is being scientific about it, and thinks the problem is that Sam is too warm "down there" due to the fact that he wears constricting bikini briefs. She suggests he try boxer shorts that contain freon to freeze his testes, which is what he becomes.
