After Lumpy Rutherford puts exploding smoke bombs in Wally's and Eddie's cars, Eddie coaxes Wally into retaliating against Lumpy with their own practical joke. But real damage is done to Lumpy's car when the joke goes wrong and Wally doesn't know that evidence left at the scene will lead the Rutherfords straight to the Cleavers. Written by
Did You Know?
At about five minutes, when Eddie and Wally are leaving the dining room and starting up the stairs, the boom mic is visible briefly in the upper left corner of the frame. This was visible on TV (not a DVD) when projected at its original standard definition, and the boom mic operator started to try to pull the mic out of the frame just as the camera moved away from it, so it's a genuine goof and not a projectionist error.
