The Big Cheese is the third part of the ninth episode of season one of Dexter's Laboratory, which aired on December 4, 1996. In this episode, Dexter says a French word that gains him fame overtime.
Dexter is in his laboratory one night getting every science experiment done quickly, and this is on the same night he had to study for a French test. At bedtime, Dexter takes his invention that gives him the option to learn while asleep and puts it on his head, inserting a French language instruction record the player. As Dexter is sleeping the night away, the record skips over "omelette du fromage," and when Dexter wakes up the next morning, he says the exact same word to Dee Dee. Teasingly she asks him her name, and despite his effort answers, "omelette du fromage", revealing to his horror that it is all he can say, which causes her to taunt him relentlessly. In French class that following morning, Dexter takes a test which he gets an A+ on. In math class, his only word becomes the correct answer for the question.
At recess, Dee Dee continues to taunt Dexter, only to have him repeat his phrase to his sister angrily. This grabs the attention of two girls, and they both go over to Dexter and fall in love with him. Five more girls (now total of seven) gather around Dexter, which makes three bullies walk over to the pint-sized scientist to hurt him. Instead, the bullies leave Dexter alone, and his phrase causes him to become an instant celebrity.
Dexter enjoys his moment of fame until he goes home to reverse the effects of the invention. However, the lab denies his phrase as an incorrect password, and he cries over his mishap while the lab triggers a self-destruct sequence as a safety measure. As a result, the lab explodes and the episode ends with Dee Dee continuing to taunt Dexter.
