Who Framed Roger Rabbit (1988)

Factual error: The picture of Eddie and Teddy on the road with dad, supposedly taken in 1906, shows a Ringling Bros and Barnum & Bailey circus poster. In 1906, the Ringling Brothers circus and the Barnum & Bailey circus were two separate circuses playing in different parts of the country. They did not combine the two shows until 1919. (00:27:00)

R.K. Maroon: How much do you know about show business, Mr. Valiant?
Eddie Valiant: Only that there is no business like it, no business I know.
R.K. Maroon: Yeah. And there's no business more expensive. I'm 25 grand over budget on the latest Baby Herman cartoon. You've seen the rabbit blowing his lines. He can't keep his mind on his job. You know why?
Eddie Valiant: One too many refrigerators dropped on his head?
R.K. Maroon: Nah, he's a toon. You can drop anything you want on his head, he'll shake it off. But break his heart, goes to pieces just like you and me.

Trivia: When the filmmakers sought permission to use the Looney Tunes characters in the film, Warner Brothers only agreed on the condition that Bugs Bunny receive equal screen time with Mickey Mouse.

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?
