In Cars 2 (2011), Finn McMissile spills oil as a way to hinder the enemy cars chasing after him. It is later revealed in this movie that oil is also their pee. Do with that information what you will.
In How To Train Your Dragon (2025) Hiccup gives Toothless to the state so he can party in college. Oh wait, that doesn't happen because that would be the stupidest thing ever.
