JURASSIC PARK (1993)
Tyrannosaurus Rex obviously doesn’t see the “Occupied” sign when, in a fit of genetically engineered rage, he forces his gigantic head into an outhouse, thereby destroying it. This kind of ruins the hiding place chosen by a cowardly lawyer (is there any other kind? Heyo!), who has taken refuge on the can. Rex then has himself a snack on the toilet, but fails to wash his hands afterwards. Gross — but in his defense, washing those hands must be a real pain due to his preposterously short arms.
