"Said the actress to the bishop" is an informal (and usually vulgar) exclamation, said for humour in the form of a punch line after an inadvertent double entendre. The equivalent phrase in North America is "that's what she said". Both phrases are examples of Wellerisms, a literal "turn" of a phrase, changing its meaning. The versatility of the phrase and its popularity lead some to consider it a cliché.
On occasion, the gender may be swapped, as in "said the bishop to the actress", or "that's what he said".
Famous quotes containing the words actress and/or bishop:
“An actress reading a part for the first time tries many ways to say the same line before she settles into the one she believes suits the character and situation best. There’s an aspect of the rehearsing actress about the girl on the verge of her teens. Playfully, she is starting to try out ways to be a grown-up person.”
—Stella Chess (20th century)
“Whether they knew or not,
Goldsmith and Burke, Swift and the Bishop of Cloyne
All hated Whiggery; but what is Whiggery?
A levelling, rancorous, rational sort of mind
That never looked out of the eye of a saint
Or out of drunkard’s eye.”
—William Butler Yeats (1865–1939)
