While they are there, Homer smells cake, and a couple of sniffs later, figures out what it says. Meanwhile, the newspaper staff is having a retirement party for their over-finicky food critic. Homer crashes the party and starts pigging out on the food. The editor, seeing Homer's liking for food, offers him a job as their food critic. He asks Homer to prepare a 500-word sample review first. Homer thanks him for the opportunity.
At home, Homer gets to work. Since the E's do not work on his typewriter, he titles the review "Food Box: Go or No Go", by Bill Simpson. When he submits the review for evaluation, the editor has a nice laugh, due to the many typos, threatening references to the UN and the many concluding "Screw Flanders". Homer, acting as if the review was a joke, says he will get the "real" one.
At home, Lisa helps out Homer. Putting Homer's gestures into words, she prepares a glowing review. On reading the "real" review, the editor is mighty impressed and declares that this is page-one material (of Section H-2).
To celebrate Homer's new job, the family goes to The Sea Captain's restaurant, The Frying Dutchman. There, people overhear that Homer's a food critic. Captain McCallister brings along a "Critic Special" meal for them, where moving creatures signify freshness. Homer also visits Planet Springfield and a revolving restaurant. He gives all the restaurants he visits great reviews, his lowest rating being "seven thumbs up." Soon, everyone in Springfield has put on weight, eating in all of Homer's well-reviewed restaurants.
At the Springfield Shopper office, the editor introduces Homer to other critics. They chide him for being too generous in his reviews. Homer, giving in to peer pressure, decides to give out bad reviews. His next review is at a dinner theater, where Krusty gives a terrible rendition of King Lear, thinking it to be a comedy. Homer gives the food and the acting a scathing review, much to Lisa's discomfort. He continues the trend at Luigi's restaurant. Marge is given only "seven thumbs up" for her pork chops.
Lisa argues with him for being needlessly cruel, but he retorts saying that people will think what he wants them to think. Having had enough, she quits. Homer declares that he is a powerful person, who'll never get his comeuppance. Homer decides to do the reviews himself, though he does take some help from Maggie and Santa's Little Helper. On reading the baby- and dog-assisted review, the editor tells Homer to shape up as the Taste of Springfield food festival is coming up and he will be reviewing all restaurants in town. He also reminds him about having expectation in the Life Ways section like astrology, Broom Hilda, and articles about Chronic Fatigue Syndrome.
Meanwhile, the restaurateurs hold a secret meeting, regarding Homer's reviews. Luigi complains that he put a horse's head in Homer's bed as a warning, but Homer ate the head and gave it a better review than he gave Luigi. Soon, they decide to kill him. A French chef (of The French Confection) declares that he will do the deed, by feeding Homer an éclair containing one million calories and 25 pounds of butter per square inch covered in chocolate so dark light can not escape its surface. For good measure, he will also add some poison.
At the food festival, despite Marge's women's intuition, Homer goes on his reviewing duties. Meanwhile, the French chef prepares the deadly piece of confectionery (with his unnamed assistant who accidentally starts adding antidote but quickly stops). Bart overhears some of the restaurateurs discussing the murder plot and alerts Marge and Lisa. They split up, looking for him before it is too late. Marge took the Fried Foods section, Bart took the Salty Snacks section, and Lisa took the desserts section. Homer, meanwhile, has reached the French chef's stall and is about to eat the éclair. Lisa runs up and shouts that it is poisoned, but when Homer shrugs it off, she yells that it is low-fat. Homer chucks the lethal treat away in revulsion, causing it to explode harmlessly, leaving a large crater on the ground.
The French chef is apprehended by Springfield's finest, but, predictably, escapes. Homer thanks Lisa for saving his life and is relieved that he did not get his comeuppance. As he and Lisa walk away, an angry mob runs after them. As the scene fades to black, Homer gets beaten up, finally getting his comeuppance.
