Some episodes are available on video with scenes of nudity included which are not shown in syndication.
In episode "The Origin of Species" there's a scene where everybody is unconscious and nude with four women shown topless. That scene was re-shot for syndication with the four actresses arms crossed over their breasts.
In the episode "Valerie 23" Sofia Shinas appears naked before her creator when trying to seduce him. In the syndicated version this shot was cut.
