Homer's Chair Can't Fall Over
S10E02 - The Wizard of Evergreen Terrace
Homer becomes depressed after learning he has lived past the halfway point of the average life expectancy for men without accomplishing anything worthwhile. His family tries to cheer him up by showing him a film of his accomplishments and a special appearance by the character KITT from the Knight Rider television series that Homer is a fan of. When the film projector stops working, Lisa mentions that Thomas Edison invented the projector and many other inventions. Homer decides to learn more about Edison and eventually idolizes him. In an attempt to follow his footsteps, he quits his job at the power plant to become an inventor.
The family disapproves of his first few inventions, including a make-up shotgun, electric hammer, alarm that never stops beeping, and reclining chair with a built-in toilet, making Homer more depressed. However, they like one particular invention, a chair with two hinged legs on the back, making it impossible to tip over backwards. Homer is encouraged until he notices his poster of Edison shows him sitting in the same type of chair. Bart points out that the chair is not featured on a list of Edison's inventions, meaning he never told anyone of this invention.
Homer and Bart travel to the Thomas Edison National Historical Park in West Orange, New Jersey, with his electric hammer to destroy the chair, but Homer notices a poster of Edison comparing himself to Leonardo da Vinci, much like how Homer compared himself to Edison. Feeling a renewed connection to Edison, he decides not to destroy the chair.
Homer and Bart return to Springfield, unaware they left Homer's electric hammer at the museum. Later when the family watches the news on television, Kent Brockman announces that the chair and electric hammer have been discovered at the Edison Museum and are expected to generate millions for Edison's already wealthy heirs, to the ire of the family.
