Polari is a form of slang or cant historically used in Britain by some actors, circus and fairground showmen, professional wrestlers, merchant navy sailors, criminals and sex workers, and particularly among the gay subculture. There is some debate about its origins, but it can be traced to at least the 19th century and possibly as early as the 16th century. Polari has a long-standing connection with Punch and Judy street puppeteers, who traditionally used it to converse.

Filthy Rich & Catflap is a BBC sitcom produced in 1986 and broadcast in 1987. The series featured former The Young Ones co-stars Nigel Planer, Rik Mayall and Adrian Edmondson as its three titular characters. It was written by Ben Elton, and produced and directed by Paul Jackson, with film sequences directed by Ed Bye. The show's music was written by Peter Brewis. One series consisting of six half-hour episodes was produced. Despite the continuity announcer saying that the show would return the following year, only one series was ever made due to a fall-out between Mayall and Elton over creative control.
