Coyote and Road Runner Coyote in the batman suit. Plot Introduction The title card is shown as a billboard behind which Wile E. Coyote is hiding, ready to chase the Road Runner. He starts the chase, until he runs into a large truck. Wile E. runs the other way, and the truck shows the credit. The chase ends in a win for the truck, and the Coyote emerges battered. A box with director Chuck Jones credit then squashes him. The Coyote throws the box away, and the shot freezes COYOTE Eatius Birdius . He resumes the chase, which freezes to show the Road Runner Delicius Delicius . The chase continues down the road until the Road Runner makes a U turn. The Coyote turns around, then stops. The Road Runner completes the circuit around, meanwhile, and beeps as the Coyote turns around, causing him to leap back. The Road Runner starts off down the road and loosens it from its hinge briefly. Wile E. points worriedly and displays an EGAD sign, then an sign. He drops them and thinks of his new plan. 1. Wile E. hides in a manhole, and as the Road Runner passes over him, he pops out and fires a rifle. The bullet and the Road Runner are shown in slow time, with the bullet closing to within a half body length of the bird. Then the Road Runner turns to notice the threat, lets out a beep and gears into super speed. The bullet then brakes in puzzlement and falls to the ground. Wile E. picks it up, and then it detonates.

From A to ZZZZ is a 1953 animated cartoon short by Chuck Jones in the Looney Tunes series. It was released by Warner Bros. in 1954 . Plot The cartoon begins with an exterior shot of a school classroom. Through the windows, children are visible at their desks. They are learning arithmetic by rote. The main character, Ralph Phillips , is bored with this lesson on seeing a bird outside, he imagines that he is free to use his arms and legs to propel himself through the air. Miss Wallace interrupts this daydream and assigns Ralph to solve a column of numbers on the blackboard. He is intimidated so much that the numbers come to life. He fights back by using letters as weapons. Miss Wallace brings Ralph back to reality and sends him out to mail a letter. He responds by becoming a Pony Express courier who braves a horde of Indigenous peoples of the Americas Indian s across his desert journey. Back in the classroom, he finds the geography lesson tedious until the sight of a fish in an aquarium triggers his next daydream as a deep sea diver who kills a shark and rescues an immobilized submarine, before a tentacle from an octopus grabs him away. Miss Wallace loses her patience and sends Ralph to the corner, but this doesn t stop him from turning the classroom into a boxing ring. On being sent home, Ralph imagines himself as Douglas MacArthur and repeats the general s most famous line, I shall return. Notes This cartoon received an Academy Award for Animated Short Film nomination in 1953 even though it did not go into general release until October 16, 1954. ref http www.davemackey.com animation wb 1954.html Warner Bros.
