Chummy was a popular prisoner of The Tank aboard Red Dwarf. His twin brother, Saddo, was also a prisoner. Chummy is seen briefly, and remains unnamed, in the broadcast version of "Krytie TV", as the prisoner Rimmer rats out to Warden Ackerman as being the thief of Ackerman's glass eye, since Rimmer had seen Chummy "playing marbles with it this morning". Chummy swings for Rimmer, but misses as Rimmer ducks, and the guards cart Chummy off. Rimmer was thinking of the appeal, but the other prisoners beat up Rimmer for being a snitch.
