Liz Hurley's boobs bounce when she is trying to get comfortable on the couch.

In the midst of a car chase, the Martian shrinks the car and drives through a sewer system. The car comes up in a toilet. We get the toilet-eye view of an overweight man pulling down his pants to sit. No bare buttocks are shown, but the shadow of his buttocks is.

Zoot slaps a woman on the buttocks twice.

Several sexual comments are made throughout the movie. Words including "pervert", "kinky", "lecherous", "contraception" and "lust" are used, while there are a few double entendres like "balls", "Uranus", "virgin wool".

It is implied that a woman tries to seduce 2 men.

With Zoot now off him, it's implied that Martin (as a human) is nude, and when he physically impersonates Tim, he's also nude and walks up and greets Lizzie who's shocked at that nudity. During this, we see a shot from behind him that shows most of his bare butt.

A couple of people start metamorping into aliens.

A man is killed when he is thrown into a bunch of computers. Another is eaten by an alien creature (not graphic).

Martin's appendages fall apart. (It looks like a mannaquin more than anything violent.)

Martin's attanae are pulled out of his head.

Pratfalls, slapstick violence and punching is done for physical comedy.
