Red Dwarf S7 Episode 1 - Tikka to Ride (1997)

The crew find themselves resurrected due to the time paradox resulting from the battle with their future selves. The time paradox also results in a greatly upgraded and much larger Starbug. However, the curry supplies have gone missing, and so Lister devises a sneaky plan which involves swapping Kryten's head, once again utilising the time machine, and which ultimately results in the crew getting mixed up in the assassination of President Kennedy in Dallas, in 1963.
