Lisa the Vegetarian

Plot

The Simpson family goes to a fairy tale amusement park. At the petting zoo, a lamb captivates Lisa. That evening, Marge cooks lamb chops. Disturbed by the link between the living animal and her meal, Lisa chooses to stop eating meat.

Homer and Bart relentlessly mock her decision. School proves no better: when Lisa refuses to dissect a worm and asks for a vegetarian lunch option, Principal Skinner calls her an agitator. Forced to watch a Meat Council propaganda film starring Troy McClure that attacks vegetarianism, her classmates then tease and shun her. Envious of Ned Flanders' barbecue, Homer throws his own with a roast pig.

Lisa prepares gazpacho as a meat-free dish, but the guests laugh at her. After Homer accidentally flips a burger into her room, hitting her in the face, an angry Lisa stops the party by driving a riding mower away with the pig. Homer and Bart chase her, but she pushes the pig off a slope. It tumbles into a river and gets launched into the air by a dam spillway.

Back home, Homer is furious; Lisa scolds him for serving meat. The next morning at breakfast, Homer's words push Lisa past her limit, and she runs away. Eventually, she gives in and bites a hot dog from the Kwik-E-Mart roller grill. But Apu, a strict vegan, tells her it is a tofu dog.

He leads her through a secret passage to the roof, where Paul and Linda McCartney are waiting. The McCartneys, old friends of Apu from Paul's time in India, are vegetarians. Apu asks what happened at home. After Lisa explains, he helps her see she was intolerant of others' views.

Lisa renews her commitment to vegetarianism but resolves not to force her beliefs on anyone. On her way home, she meets Homer, who is desperately searching for her. He apologizes, admitting he and Bart went too far. Lisa also apologizes for wrecking his party.

Homer forgives her and offers a veggie-back ride home. During the end credits, the roasted pig is still flying through the air.

Production

David X. Cohen, then known as David S. Cohen, wrote "Lisa the Vegetarian" as his first full-length episode for The Simpsons. The concept emerged while he was distracted by hunger during another script; he jotted down "Lisa becomes a vegetarian?" on the back of a page. Showrunner David Mirkin, who had recently adopted a vegetarian diet, greenlit the story. Writer Bill Oakley suggested the barbecue sequences, noting that Cohen's initial draft featured a more abstract debate about meat consumption and needed a concrete conflict. George Meyer contributed the visual joke of the barbecue pig becoming airborne after getting stuck in a spillway. Cohen attributed the scene where Homer cannot grasp that bacon, ham, and pork chops all come from the same animal to a genuine remark by writer John Swartzwelder, who marveled at the pig's versatility.

Cultural references

The episode is packed with nods to the Beatles and Paul McCartney’s solo work. When Paul hears Lisa has run off, he exclaims, “What? She’s leaving home?,” echoing the Beatles song. Linda mentions that she and Paul enjoy relaxing “in Apu’s garden in the shade,” a wink at “Octopus’s Garden.” Apu brags that during the Maharishi era, he was considered the fifth Beatle.

Paul tells Lisa that playing “Maybe I’m Amazed” backwards reveals a recipe for lentil soup; a modified version plays over the credits, and when reversed, Paul recites the recipe. One backward snippet says, “Oh, and by the way, I’m alive,” poking fun at the “Paul is dead” rumor. Linda promotes her own vegetarian food line. Apu wears a shirt reading “Don’t have a cow, man!,” a twist on Bart’s catchphrase.

Lisa’s encounter with a lamb followed by being served lamb mirrors how the McCartneys became vegetarians in 1975 after watching lambs play while eating lamb chops. Later, Apu sings a bit of “Sgt. Pepper’s Lonely Hearts Club Band,” with the McCartneys snapping along as Lisa cringes at his off-key singing.

Reception

The episode debuted on Fox on October 15, 1995. It ranked 47th for the week of October 9–15, earning a 9.0 Nielsen rating, which translates to about 8.63 million households. That week, it was Fox’s fourth most-watched program. It took home an Environmental Media Award for Best Television Episodic Comedy and a Genesis Award for Best Television Comedy Series, Ongoing Commitment. Critics and the show’s staff hold it in high regard; showrunner David Mirkin, director Mark Kirkland, creator Matt Groening, and writer Ian Maxtone-Graham count it among their favorites. Mirkin called the petting zoo opening one of the series’ best sequences, praising Kirkland’s animation. He also liked Apu’s role, noting he shows Lisa that change comes through tolerance. Groening views the family conga line as a series high point.
