Watch Dexter's Laboratory

Dexter’s Laboratory is a classic CartoonNetwork cartoon. It centers on a child super genius named Dexter, who is always coming up with crazy inventions in the hidden laboratory beneath his house. For the most part, Dexter has some fool proof inventions but things never seem to go right with his older ditzy sister, Dee Dee, constantly pestering him. Like the experimental cookies Dee Dee accidentally ate which made her grow massive, turning the city into her personal doll house. Or when he builds an exo-suit to help him win at dodge ball.

As if Dee Dee wasn’t enough of a problem, a new student is enrolled at Dexter’s school. The snarky Mandark Astronomonov is another child genius who claims to be better than Dexter both academically and scientifically. Upset, Dexter is not giving up easily. He teams up with Dee Dee to get revenge, which sparks a lifelong rivalry between the two scientists.
