Homer gets a new assistant that soon replaces him while Bart and Martin create a robot seal that becomes a hit with the elderly crowd at the Springfield Retirement Center.

!! Tropes:

* AlliterativeName: Bart projects a machine known as "Homer Humiliator".
* ComicallyMissingThePoint: Homer doesn't understand why the Homer Humiliator does mean things to him.
* ExactlyWhatItSaysOnTheTin: The Homer Humiliator humiliates Homer Simpson.
* FunWithAcronyms: The '''N'''orth '''A'''merican '''M'''an '''B'''ot '''L'''ove '''A'''ssociation. Understandably, not all members agree with the name.
* ShoutOut: ''[[{{WesternAnimation/Futurama}} Bender]]'' was at the front page of a robotics magazine and Santa's Little Helper had a ''[[Franchise/StarWars Darth Vader mask]]''. Homer leaves work sooner to watch [[Film/PaulBlartMallCop Paul Flart: Water Park Cop]].
