"As the actress said to the bishop" first appeared in one of the �Saint' books by Leslie Charteris in 1935. The actual quote there was: "What's in a name? - as the actress said to the bishop when he told her she reminded him of Aspasia." (Aspasia was the mistress of Pericles in ancient Athens, notorious for her naughty private life.) On a similar basis today, the phrase is invariably used as a suggestion of sexual impropriety often in the form of a double entendre.
