The First Official "Cartoon Cartoon":
Dexter's Laboratory debuted on Cartoon Network's World Premiere Toons (later known as What a Cartoon!) in 1995. It was the very first series greenlit as a full Cartoon Cartoon original, effectively launching the golden era of Cartoon Network originals that included The Powerpuff Girls, Johnny Bravo, and Courage the Cowardly Dog.
Genndy Tartakovsky’s Breakthrough Masterpiece:
The show was created by legendary animator Genndy Tartakovsky, who drew Dexter based on a quick student sketch of a small, rectangular boy. Tartakovsky later went on to create industry-defining masterpieces like Samurai Jack, Star Wars: Clone Wars (2003), and Primal.
The Secret Behind Dexter’s Accent:
Dexter speaks in an exaggerated, undefined European/German-French-Russian accent, despite growing up in a typical American suburban home. Tartakovsky explained that Dexter’s accent comes from the fact that all the greatest scientific minds Dexter idolized (like Albert Einstein) spoke with European accents, so Dexter simply taught himself to speak like them.
"Omelette du Fromage":
One of the most famous episodes in television history ("The Big Cheese") features Dexter accidentally getting stuck only being able to say "Omelette du Fromage" due to a malfunctioning sleep-learning record. The phrase became a massive worldwide meme and one of the most quoted lines of 90s animation.
The Unseen Footprint of Dee Dee:
Dexter’s tall, hyperactive sister Dee Dee was intentionally designed as the complete geometric opposite of Dexter—tall, circular, light-pink, and fluid in motion, whereas Dexter was short, square-jawed, dark-toned, and rigid. This stark contrast made their chaotic sibling dynamic visually iconic.
