Lumpy puts smoke bombs in both Wally and Eddie's car engines, rendering both cars temporarily immobile. Wally and Eddie decide to get back at Lumpy, but for Wally only if the prank is funny but harmless. After discarding several other pranks as either too dangerous or juvenile, they decide to use Ward's tow chain to wrap around Lumpy's rear axle while wrapping the other end around a tree, so that Lumpy will stall when trying to drive his car out of the driveway. The prank ends up being a little more harmful than they anticipated as when Lumpy tries to drive off, the entire rear axle of his car falls off. Wally and Eddie have to decide what to do. But if Lumpy and Mr. Rutherford discover it was them that pulled the prank, will Lumpy confess to having started the war of the pranks?
