In the latest Futurama episode, there was a scene with the dialogue:
Professor: Now, for the first time, we may be able to see the infinitesimal fabric of matter itself, laying bare the most fundamental laws of the universe.
Leela (whispering): Hey, Fry, I know something you could lay bare.
Fry (obviously not getting it): Leela, shh, I'm trying to listen to a physics lecture.
... a few seconds later in the episode ...
Professor: Now, to penetrate its deepest mysteries.
Leela (whispering): Hey, Fry.
Fry: Leela! No means no!
Obviously, in the second scene, where Leela was cut by Fry, she meant to say, "Hey Fry, I know what you could penetrate." The irony was in Fry not getting it all the time. What I don't understand is: what does the first Leela's proposal mean (marked bold in the dialogue)?
