Red Dwarf S07E01 - Tikka to Ride

The crew are dead, slain by their future selves in the cliff-hanger that ended series six. But coming back from the dead is a piece of cake compared to the real dilemma confronting Lister - the curry supplies have been destroyed and he's three million light years from the nearest poppadom. Unable to face cold turkey vindaloo style, he ignores causality and goes back in time intending to order "500 vindaloos to go" but winds up in Dallas, in November 1963, where he accidentally pushes a gunman out of a fifth floor window.
