The phrase "said the actress to the bishop" is a colloquial British exclamation, offering humour by serving as a punch line that exposes an unintended double entendre.
[4] The phrase is frequently used by the fictional character Simon Templar (alias "The Saint") in a long-running series of mystery books by Leslie Charteris.
to draw attention to double entendres, briefly toyed with "...said Ripley to the android Bishop", a reference to both this phrase and the 1986 film Aliens.
[9] In the original BBC version of The Office, Ricky Gervais's character David Brent frequently used the phrase "as the actress said to the bishop" as an inappropriate joke.
When the show was adapted for American audiences, also under the title The Office, the phrase was translated to "that's what she said" for Steve Carell's character Michael Scott.
