Gizmo Shmizmo - S5.E9

Loonette has installed a couch gizmo that will fetch her toys for her. But the gizmo malfunctions, spitting out ping-pong balls at an enormous rate. She tries to get Major Bedhead to help, but he shows off his own gizmo, which doesn't work either. Granny tells them (through a song) that it's better to rely on one's mind than on machines.
