Terry and Julian is a British sitcom that aired on Channel 4 in 1992. Starring Julian Clary, it was written by Clary, Paul Merton and John Henderson. The title is a spoof the title of the long-running BBC sitcom "Terry and June", whose star June Whitfield made a guest appearance in one episode of "Terry and Julian". Using only the above description and what you know about the world, ""Terry and Julian" writer Paul Merton hasn't written anything aired on the BBC." is definitely correct, incorrect, or inconclusive?
