that's not what your mother said last night

similar to that's the sound your mother made last night. it also originated from SNL celebrity jeopardy. it was said by Sean Connery and is just another sexual innuendo.

Sean Connery: It's been a long time, Trebek.
Trebek: Not long enough.
Sean Connery: That's not what your mother said last night!
