Edgar Buchanan, who had guest-starred as Captain Jack in the very first Leave It to Beaver episode, returns to the series as the Cleaver boys' lovable Uncle Billy. Though everyone in the family knows that Billy is prone to spinning tall tales, Beaver (Jerry Mathers) believes every word that he says. A crisis soon develops when Beaver makes it clear that he expects Uncle Billy keep his "promise" about buying him a new fishing reel. ~ Hal Erickson, Rovi
