Oversexed Rugsuckers From Mars

Tiny Martians use Earth as a lab to try out new life forms. Returning after 10 million years only to find that the human experiment is a failure.

They decide to mate a human with a vacuum cleaner to create a species that will be better at cleaning up after itself, but a programming error by a drunken Martian sends the oversexed cleaner on a wild rampage of rape, murder & overall bad manners.
