Nudge nudge is a sketch from Monty Python's Flying Circus. It usually features Eric Idle and Terry Jones as two strangers who meet in a pub. Idle, playing a younger man, asks Jones, as an older gentlemen, several questions about his relationship with his wife, all bearing hidden sexual innuendo ("Does you wife 'go,'" "is she into sport," "is she interested in photography," "likes games, eh?," "candid photography," etc.), and all followed with "Nudge nudge, wink wink, know what I mean, know what I mean, say no more, say no more," from which the older man is supposed to glean the sexual connotations of his questions. Eventually, the older man has had enough and demands that Idle be direct with him, so Idle asks him what it is like to sleep with a woman.

The sketch was later adapted as a commercial for Breakaway chocolate biscuits ("suggestive...digestive...know what I mean?").

On the version of the original sketch as performed at Drury Lane , after the commercial has become well-known, Idle adds the line "Ugh...Breakaway! Eurgh!" and gets a huge laugh.
