The Simpsons Episode 7.07 King-Size Homer

Sick of the workaday grind at the Springfield Nuclear Power Plant, Homer comes up with a scheme to gain enough weight to be classified as disabled, thereby earning the right to work from home. With a target weight of 300 pounds in mind, he eats everything in site, including Maggie's Play-Doh. Fat as a tick, Homer is granted his wish to work from home, but it's not all he thought it would be when he finds that he's too fat to stop an imminent disaster in the plant's reactor core. The only thing big enough to stop the explosion is Homer's enormous body, which he manages to wedge into an exploding tank. Having saved the plant and the town, he is rewarded for his efforts with a free liposuction courtesy of Mr. Burns.
