Piggy Tales - Season 2 Episode 16 All Geared Up

A black-and-white film shows a worker pig who fails incoming inspection by wearing a bucket for a hat instead of a construction hat. Later, the pig is on an assembly line, trying to put parts involving a wheel and a board together. The conveyor belt goes faster with more parts until the worker is exhausted. The scene expands to show a third pig taking the parts that have fallen off the belt and putting them back at the start.
