 The title of Shakespeare's play "Much Ado About Nothing" is a pun on the Elizabethan use of "no-thing" as slang for vagina.In the UK, starting in the 19th century, Victorian morality disallowed sexual innuendo in the theatre as being unpleasant, particularly for the ladies in the audience.In music hall songs, on the other hand, this kind of innuendo remained very popular.
