Homer becomes an inventor after realizing his life is almost half over and he hasn't done anything that will be considered a legacy.
- Bungling Inventor: Homer's first inventions are generally terrible, unless that is anyone out there feels the need for an everything's-OK-alarm, a make-up shotgun, or an armchair toilet.
- Foreshadowing: Homer falling over in his chair while the kids were visiting him in his invention workshop.
- Home Made Inventions
- It's Been Done: After several disasters, the one invention that works turns out to have been invented by Edison himself but apparently unnoticed, prompting Homer and Bart to travel to Edison's workshop to destroy it. Homer decides not to once he sees that Edison himself also had a "rivalry" similar to his with Leonardo da Vinci. Homer decides to split the difference and take both his and Edison's frustrations out on the Eli Whitney museum.
- Lonely Funeral: Homer imagines himself dying: In Homer's imagination, the gates to the Graveyard of the Future open, where his funeral is taking place. Ned Flanders does the ceremony, while a suited Lenny and two bodyguards, Barney Gumble with his arms full of Oscars, as well as the robot from Lostin Space and Heckle and Jeckle, stand by.
Ned: No, Homer wasn't a great man, nor even an adequate man. And he certainly never accomplished anything. Uh, President Lenny, do you have anything to say?
Ned: All right, fair enough. Toss him in the hole, boys.

Heckle: There goes a real sack of crap!
Jeckle: Indubitably, old chum! (several dogs start to chew on Homer's feet)
- Noodle Incident: Homer getting kicked out the adults' library and quitting his job.
- People Fall Off Chairs
- Royalties Heir: One of Homer's inventions (an electric hammer) is making millions. Unfortunately, for his family, the invention was credited to Thomas Edison, the royalties went to his "already wealthy" heirs.
- Tim Taylor Technology: When Homer first showed off his electric hammer, it goes haywire and starts dragging him across the floor. He turns it off and concludes, "Probably needs to be more powerful."
