Beaver (Jerry Mathers) shells out good coin for a mail-order magic trick, but no one seems impressed by his conjuring skills. In desperation, Beaver and Larry (Rusty Stevens) put on a mini-magic show for the only person willing to watch: four-year-old Benjie Bellamy (Joey Scott). Larry covers Beav with a cloak, says the magic words and -- presto -- Beaver is gone and a rock is in his place. The astonished Benjie is now convinced that Beaver has turned into a rock, and cannot be convinced otherwise. The situation gets stickier when Benjie's mom insists to Ward (Hugh Beaumont) and June (Barbara Billingsley) that Beaver immediately reveal himself to mollify her fretting son -- something that just isn't possible at the moment!
