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. (thetvdb.com)
