Techno-Cracked is a theatrical animated short film, directed by Ub Iwerks and featuring Flip the Frog.
[1] In this satire of the Technocracy, Flip the Frog is nearly killed by a menacing robot he builds to work for him.
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.
When the robot mows the welcome mat it reveals the word Nerts, a possible reference to either the card game or to a popular expression of the time -- "nertz".
