“that’s what she said” will do about as well as “said the actress to the bishop” and you don’t have to spend a lot of time explaining “actresses” or “bishops” to the culturally illiterate.
I have been having a lot of fun with the age-old “I got yer ______ (lampshade, copier, submarine, definition of God, whatever) right here” line lately. The more obtuse the reference, the better, it seems.
Example:
“I got yer obtuse right here!”
