“One Got Fat” is a twisted 1963 bike safety movie where ten frighteningly-clad monkey children are picked off one by one as the result of their ignorance and sloth regarding simple bike safety. It’s final scene depicts Orville, the final survivor. He sits alone, naught to keep him company but the meals of his fallen companions.
“One Got Fat” indeed.
Incidentally, you may recognize the narrator as Edward Everett Horton of Rocky and Bullwinkle (Fractured Fairy-Tales) fame.
You’ll also notice that this film was sampled heavily for the Boards Of Canada video “Everything You Do Is A Balloon”.
