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!

I slept like coarse woody debris last night. 

A foresters way to say:
"I slept like a log last night."
"I slept well last night."
"I slept like a baby!"
"That was some awesome sleep!"

"Hey! How did you sleep last night?"

"I slept like coarse woody debris last night."

"No way! That's awesome."
