Techno-Cracked is a 1933 Celebrity Productions, Inc. animated short, directed by Ub Iwerks.
In this satire of the Technocracy, Flip the Frog is nearly killed by a menacing robot he builds to work for him. Flip would rather not mow the lawn. He reads an article from "Unpopular Mechanics" entitled "Technocracy: Why be a Slave - The Mechanical Man Works While You Sleep". Flip makes his robot out of household parts but gives it a Jack-o'-lantern for a head. The mechanical man cannot follow directions and begins mowing down everything in sight. Flip blows up the robot with a stick of dynamite and finishes the lawn by himself.
