Against his better judgment, Rob (Dick Van Dyke) allows his son Ritchie (Larry Mathews) and the Helpers' son Freddie (Peter Oliphant) to be cast in a TV commercial. Just as Rob had feared, Laura (Mary Tyler Moore) and Millie Helper (Ann Morgan Guilbert) transform into the Stage Mothers from Hell, arguing over billing, number of lines, and which of the two boys' faces will be obscured by a catcher's mask. Colin Male, the announcer heard introducing the cast at the beginning of every Dick Van Dyke Show episode, makes a rare onscreen appearance.
