 Reportedly, a scene included in the theatrical release is omitted from TV and  home video releases: after the leader of the mutant bikers announces to  everyone that "they couldnt even take a shower with a beautiful woman  without wearing their jeans" they realized that the mutant bikers were  another of Lisas creations and wouldnt harm them.  With the original scene  they have an opportunity to show off for their friends.  With that scene cut  they suddenly develop courage on their own.
