Duane Dibbley first appeared in the 1992 Red Dwarf episode Back to Reality, from series five of the BBC science fiction comedy. Played by Danny John-Jules, he was introduced as the Cat's hallucinatory alter ego, a dowdy traffic warden type completely unlike the Cat's fashionable persona. The contrast made Dibbley an instant fan favourite, and he returned in later episodes and became a lasting reference among viewers. Online, clips and edits of the character are shared whenever someone undergoes an unflattering change or loses their cool in public.
