Published September 19, 2026

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." The line sat mostly dormant until Tumblr and YouTube edits turned it into a viral catchphrase in the early 2010s, later powering a 2020 Twitter clip of a fake French tourist that pulled nine million views.

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.

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

How to Use This Meme

Common uses include quoting the phrase as a reply when you don't know the answer to a question, pairing a Dexter subtitle screenshot with a school or dating scenario, or building on the "I love your accent, say it again" template with a punchline swap. The joke works best when the phrase is dropped into a situation where it does not belong.
