"King-Size Homer" is the seventh episode of Season 7.
Synopsis
Homer tries everything to get out of the plant's new exercise program and discovers that being on disability would do just that. With Bart's help, Homer begins eating whatever he could get ahold of, including Play-Doh.
Full Story
Mr. Burns organizes an exercise program at the power plant. While this program finds some support among the workers, Homer is not one of them. After learning that those on disability get to work at home (and not take part in the exercises), he tries to injure himself. But, when he discovers that hyper-obesity counts as a disability, he chooses to put on weight until he is 300 pounds. In this way, he can be legally disabled and force Burns to let him telecommute. Despite Marge's protests that this could endanger his health and jeopardize her attraction to him, Homer engages in nearly unprecedented gluttony. After a mass eating spree with Bart, he tells Homer that they're out of food, including the basics. Faced with the prospect of another day at work, Homer eats a Play-Doh donut that Maggie made. This manages to push him over the 300 pound goal due to the Play-Doh being non-toxic (much to his success), but Bart notices that Homer's gut is caught on the towel rack. Once Homer lets his gut hang down, the scale readjusts to 315 pounds, much to Homer's amazement.
A computer work station is set up in the Simpson home for Homer's position. Homer enjoys working from home, and he thinks that he will get a can of Tab if he presses the "tab" key due to his stupidity. Then, he realizes that all he had to do is to press "y" to answer "yes" on the computer, but does not read the command correctly, so he impatiently constantly presses the "y" key. However, he soon ends up tired of the repetitiveness of the situation, and begins to get distracted. Later, Homer leaves a drinking bird pressing the "y" button while he goes out to see a movie at the movie theater. After being refused to be seated due to his large 315 pound size and due to getting heckled by some people outside the movie theater, Homer returns home and is vowing to show that overweight people can be important. Upon his return, he finds out that the drinking bird has been knocked aside, and that a nuclear meltdown at the power plant is imminent, so Homer rushes to the plant and bravely tries to take charge. He ultimately saves the day when the ladder to the manual shut-off switch collapses due to his weight. He then falls into the release tube where his enormous gut gets stuck and prevents the toxic gas from escaping. As a reward and upon Homer's request, Mr. Burns guarantees that he will make Homer thin again. Later that night, after Homer fails with his exercise program, Burns chooses to just pay for the liposuction, much to Homer's joy.
