What Were the "Bleeped" Words between Frank and Loretta?

At about 20 minutes into the film, Frank McHugh's "Speed" is talking to Loretta Young's "Marcia" on the sidewalk. She asks him what he's been up to, and he says he has been writing a book. The conversation goes like this:

Speed: Just finished writing a book called, "Sex and What Causes It". [Marcia's contained smile and averting of eyes indicates an appropriate feminine modesty about the subject] It's for Bernard McGovern. Got five grand out of it."

Marcia: Five grand!!??

Speed: (Sound cuts out as Speed's lips keep moving)

Marcia: (Sound still out, but it looks as if her last two words might be "Oh, boy!"

Speed: (Sound still out at the beginning, and then:) ... [still in l]ove with him?

Marcia: No, don't be silly!

After that the sound continues as normal.

Does anyone have an original screenplay? What words were cut out?

It's possible Speed's words were just small talk about how much money he made for ghost-writing the book. But given the subject of the book, it's possible they contain a suggestive wisecrack. The print I saw may have had the wisecrack -- intended to be heard by the original pre-Code audience -- edited out, either for certain jurisdictions in 1933 or for later re-releases (after the Code came into effect).

Does anyone know anything about this? Or is anyone a good enough lip-reader to tell what Speed says?
