Tired of pushing Else around in her chair Alf feels she should have an electric scooter but they cost two and a half grand and the woman at Social Security tells Alf that, as long as he is around to push, Else is ineligible. Taking an idea from some kids with a go-kart Alf adds jet propulsion to the chair, which goes out of control, foiling a bank robbery and landing him in hospital. He is declared a hero but, following Winston's view that the robbers' accomplices may be out to get him, decides to remain anonymous.
