Tobar: I've never found any evidence of that scene. The only scene that was confirmed to have been used in the TV version was the pig-head scene, which was cut very late in the production.
I've done a few more comparisons and it seems there are some differences between the German HDTV version and the blu-ray version. In the Betty Boop nip-slip scene, there were two edited versions. The first edit, which appears on the German HDTV version, just added extra black to her dress to cover the nipples. The second edit, on the blu-ray and vista series DVD, added more black and reduced the cleavage line as well.
Also, during the scene where Jessica is thrown from the cab, there were two edited versions. The original version of the scene had three panty shots, one in each cut. The german version covers the first two shots but in the third shot, where Jessica bounces off the ground, the panties still show up briefly. In the blu-ray version this panty shot is covered up as well.
