Dana is asked to model for a melodramatic campus artist, naked. JT is interested in Karen's lab partner but she is well out of his league. There is a rat in the roof and Frank is determined to get rid of it, with little success.

Frank is caught in the middle of a dispute between Carol and his well-meaning but overbearing mother, Helen, over the rearing of baby Lily. He wants to stay out of the argument, but realizes his marriage is more important when Helen announces plans to move to Port Washington to be Lily's nanny.
