Before the accident that killed the crew, Lister belonged to a poker school aboard Red Dwarf. One of the other players was "Bent Bob", a small man with a bad toupee who worked in the catering department. (RD: Duct Soup)
Baxter once ran out of money during a poker game in The Tank and bet his right testicle on a pair of Jacks. Rimmer used this event as evidence of how tough Baxter was. (RD: Only The Good...)
Lister spent an evening playing poker against a group of BEGGs. He did so badly that he lost both Starbug and Rimmer to his opponents. (RD: Entangled)
In a scene deleted from the episode "Marooned", Lister played strip poker against Kryten and The Cat. Kryten fared very badly because he had a lot less clothes than everyone else. He had to use parts of his own body instead.
