Lumpy (Frank Bank) has been playing pranks on Wally (Tony Dow) and Eddie (Ken Osmond), the most recent of which involved planting cherry bombs in their car. Thirsting for revenge, Eddie and Wally chain Lumpy's car to a tree, then stand by to wait for the hilarious results. Alas, the gag doesn't work quite as planned, and before long Lumpy's car has been expensively torn in half -- and worse, the chain used had Ward Cleaver's name on it!
