My World and Welcome to It S01 E08 Seal in the Bedroom

Greeley rejects yet another of John's cartoons which he doesn't understand, one involving a seal in the bedroom of a married couple. Ellen and Lydia agree with Greeley, and when John tells Phil about his problem, Phil suggests the seal might represent John's mother who is visiting the Monroes. Naturally this provokes a fantasy in which John's mother, who showed up at the house wearing a sealskin coat, actually becomes a seal.
