Now this is interesting - I just checked the old FLAiR laserdisc rip, and while it has Baby Herman's extended finger, it doesn't have Betty's Boobs.

I can confirm this with my full-frame LD as well.

Rather than trying to do any repainting, they simply did a video edit cutting that frame and replacing it with a single-field pause of the previous frame. The pulldown pattern breaks, but resumes at the next shot.

No wonder I couldn't find that frame when I was looking for the timecode earlier.
