There is this movie that keep eluding me. The way I can describe it is a race to a fountain\vault of some kind that has a lot of nudity and jokes. It came on HBO or cinemax in 2000 or 1991. All remember is a lot of aliens, the sex bot in the passenger seat, and an alien girl bent over a table being tazed and her *** goes spiky then smooth. I've been looking for this for years, and I can't remember, Anyone?

A shot in the dark here... Was it maybe Heavy Metal or Heavy Metal 2?

Might it be Tripping the Rift (http://www.imdb.com/title/tt1212448/) ?
