The 1996 Dexter's Laboratory episode "The Big Cheese" gave the internet its favorite mangled French phrase when boy genius Dexter accidentally programs himself to say only "omelette du fromage."

Overview

The line comes from a single episode of Cartoon Network's Dexter's Laboratory, where the pint-sized inventor tries to cram for a French test using a sleep-learning device that gets stuck on one phrase all night. He wakes up able to say only "omelette du fromage," which somehow charms every girl in class and lands him a hit record and an impassioned speech at the UN before his lab explodes at the end1.

Online, the joke shows up as subtitle stills of Dexter whispering the phrase, image macros pairing his stunned face with mundane school scenarios, and edits that isolate the "I love your accent, say it again" exchange for parody4. In 2018, Black Twitter users started swapping Dexter's line for AAVE and slang variants, turning the classroom exchange into a rewritable joke template7.

Date

1996

On December 4, 1996, the Dexter's Laboratory episode "The Big Cheese" aired on Cartoon Network7. Dexter falls asleep with a French language tape running, but the tape skips and loops "omelette du fromage" all night, leaving him unable to say anything else the next day. The scene lives on YouTube, where an uploaded clip lets viewers hear Dexter's rapid-fire delivery of the phrase in the classroom2.

The joke sat as a cult reference for over a decade before it got a wider label. On December 12, 2009, Urban Dictionary user MrSchwab wrote an entry summarizing the episode and the line's appeal, and the definition picked up more than 1,800 upvotes over the years that followed6.

How It Spread

Momentum built on video and blog platforms in the early 2010s. On November 20, 2012, YouTube user 82percent posted a clip focused on the classroom girls swooning over Dexter's accent, which crossed one million views3. The Tumblr side grew in parallel. On March 6, 2013, user fearofwinning shared a screenshot of a fake Dexter vinyl sleeve titled "Dexter Sings Omelette du Fromage" that hit 129,000 notes, and on August 20, 2013, user tab-hoarder posted the "[whispers] Omelette du fromage" subtitle image, which reached 50,000 notes7.

Mainstream press caught up on April 14, 2017, when Vice ran the first-person piece "I Spent an Entire Day Only Saying 'Omelette Du Fromage,'" pitched as a 20-year anniversary experiment on whether the phrase brings the same run of good luck it did for Dexter1. In 2018, Black Twitter users flipped the "I love your accent, say it again" exchange into a slang-swap format, giving the line a second life as a rewritable joke4.

The 2020 US presidential election coverage brought the phrase a fresh viral moment. On November 7, 2020, Twitter user @pierre_lt posted footage of a shirtless American tourist in a Michigan cap, later identified as Meka Anyanetu, crashing a French news report in Paris to fake a French accent and declare "I love an omelette du fromage"5. Within days the clip pulled 9.2 million views, 84,000 likes and 33,000 retweets, and got tagged online as "Omelette Du Fromage Man."

The joke works best when the phrase is dropped into a situation where it does not belong.
