Red Dwarf 2x6

Parallel Universe

Believing his new “Holly Hop Drive” can return the crew to Earth in a matter of seconds, Holly instead sends them to a parallel dimension with its own Red Dwarf. In this reality, Lister is a beer-swilling tomboy, Rimmer a stilted female bureaucrat, and the Cat, to the horror of his visiting alter-ego, is a dog. In a night they’ll all regret, the crews mingle, the drink starts flowing and one thing leads to another, the repercussions for Lister being unnaturally severe.
