"The Big Cheese" is the third part of the ninth episode in the first season of Dexter's Laboratory.


Dexter's new invention allows him to study for the next day's French test during his sleep. A scratched record causes his device to repeat a single phrase, "omelette du fromage", throughout the night, and Dexter wakes up with the inability to speak anything besides that phrase.

Why It Rocks

  1. The start was very nice, with Dexter doing the tasks on his to-do-list in his laboratory.
  2. The invention Dexter uses to study for his French test while sleeping looks pretty cool and impressive.
  3. Speaking of which, the person that narrates the learning French CD has a smooth voice and does a great job teaching to the point where Dexter could only say "omelette du fromage" (French for "cheese omelette").
  4. Dexter only saying said two words does great things for him, with himself passing his French test, being right in maths when saying that the cars will collide in the French city of omelette du fromage, making the girls fall in love and calming down the bullies, and even becoming famous after answering the same question in a quiz show.
  5. Watching the montage of Dexter becoming rich was also nice and amazing.
  6. "Omelette du Fromage"

Bad Qualities

  1. The cheese omelette translation is actually incorrect here, as it's actually "omelette au fromage" instead of "dú".
    • On top of that, the city of omelette du fromage doesn't even exist in real life.
  2. Dee Dee is still annoying for constantly making fun of Dexter just for saying one word, but thankfully she only appears briefly at the start & end.
  3. Bad Ending: Although Dexter becomes rich and famous, he doesn't get access to his laboratory due to him only saying "omelette du fromage", and it ends with his lab exploding to pieces and Dee Dee saying that it's all Dexter can say.


  • It holds a rating of 7.8/10 on IMDB.


  • This episode may be inspired by Steve Martin's stand-up routine about speaking French. [1]
  • The password Dexter speaks at the start, "Star Wars" is a reference to the well-known science fiction movie series.
  • The iconic quote became a definition in the dictionary on December 2009.
