Who Framed Roger Rabbit (1988)

Revealing mistake: When the weasels are at Eddie's apartment and Roger is handcuffed to Eddie, Roger runs under the bed and drags Eddie on the floor. As he pulls him you can clearly see a board with wheels under Eddie that is pulling him under the bed. (00:38:50)

Eddie Valiant: I'm through with taking falls. And bouncing off the walls. Without that gun, I'd have some fun. I'd kick you in the...
[A vase hits Eddie in the head stopping his singing.]
Roger Rabbit: Nose.
Smart Ass: Nose? That don't rhyme with walls.
Eddie Valiant: But this does.
[Kicks Smart Ass in the balls].

Trivia: After reading Judge Doom's introduction and that the character never blinks, Christopher Lloyd immediately realised that Judge Doom was a toon.

Question: Does "pattycake" also mean something sexual? We were obviously at first supposed to think Jessica and Acme had sex, but if they were, why would she say "pattycake" and why does Maroon say "You're not the first guy whose wife went pattycake on him"? Am I missing out on something?
