Out of the Mouths of Babes - S7.E24

Darrin gets changed into a little boy again when he bans Endora from taking Tabitha to a supernatural event. As a boy, Darrin beats the pants off of a few boys in a basketball game. One of the boys, Herbie, wants Darrin to play in a championship game. Darrin, throughout all this, is in the middle of working on a new account for Irish Stew which is not selling at all, but by the end, the stew is fit for dogs.
