Q. What's the best known TV catchphrase

A. Victor Meldrew's "I don't believe it!", spoken by Richard Wilson in One Foot in the Grave, has been voted the greatest comedy slogan of all time. In a Radio Times poll, 42,5 per cent of voters plumped for his catchphrase. Del Boy Trotter's expression "Lovely jubbly", from Only Fools and Horses, was runner-up. nearly 20 per cent of voters chose "You dirty old man", from a BBC classic Steptoe and Son. Two modern comedies provided the fourth and fifth favourites - "Are you local ", from The League of Gentlemen, and "..which was nice," from The Fast Show.

Best slapstick sitcom moment was from the Fawlty Towers gourmet night episode, where Basil Fawlty (John Cleese), finds his duck a l'orange is in fact a blancmange. It was followed by Frank Spencer (Michael Crawford) dangling over a cliff in Some Mothers Do 'Ave 'Em and Margo Leadbetter (Penelope Keith) falling in the mud in The Good Life.
