Watch My Line - S2.E20

The art of cartoon drawing is demonstrated by an animator, whom Bugs directs to draw a line that becomes a dog's wagging tail for a story of canine mistreatment by an innocent, little girl, and then to sketch a pair of speedy legs- those of the Road Runner, as a start to a Road Runner cartoon containing Wile E. Coyote's dynamite stick on a lasso, giant coil spring, dehydrated boulders, and steam roller- all ineffective at ending the Road Runner's life in the fast lane. The animator next turns mischievous and puts Bugs through various indignities.
