Wabbit Twouble (1941)

The sign greeting campers says, "Welcome to Jellostone National Park: A Restful Retreat." Elmer Fudd finds this to be a dirty lie when Bugs Bunny torments him for the fun of it. Bugs will trick Elmer into thinking day is night, mid-air is safe ground, and his rabbity self is a grizzly bear before Elmer commits an act he'll immediately regret.
