Robert hopes a stray mutt will replace Nicholas' imaginary friend -- if they can keep the pup hidden from pooch-hater Jerri. The school psychologist convinces Robert than an imaginary friend is completely normal -- but when he relievedly tells Jerri about the dog, Jerri and the psychologist are convinced he's the delusional one.

On the eve of Jerri's graduation from law school, her ""stay-at-home, full-service"" mother Elizabeth objects to her putting career before family, and announces that she is moving in as a full-time housekeeper. Meanwhile, Wendell gets bad news over the psychic hotline.
