Dexter's Laboratory on Cartoon Network

Science is awesome! In Season 6, there's more fun than you could fit in a bazillion test tubes. Dee Dee teaches Dexter a lesson in judo and shows him how blondes have more fun. Dexter is forced to team up with his geeky rival, Mandark, to compete with a new girl genius at school. And in an effort to make up for his lack of height, Dexter tries to shrink the rest of the world!

In Season 5, the experiments in weirdness continue when Mandark poses as Dexter's mother and winds up kissing Dexter goodnight-SICK! Dexter discovers that trying to turn his sister Dee Dee into a boy is a huge mistake. And when Dexter goes to college, he invents the world's biggest hot tub and gets himself (and the whole university) into hot water.

For Dexter, every day is an experiment in mayhem. But a true hero always masterminds his way out of trouble! This season he concocts a plan to give Dee Dee a better brain, she turns him from a quiet creator to a mad destroyer, and Mandark tries to win Dee Dee's love while plotting to take over Dexter's beloved lab. Just a day in the life of a not so average third grade grader!

Dexter, the genius third-grader faces normal struggles like annoying sisters and school bullies, but his experiments are totally abnormal! In Season 2, Dexter is forced to team up with his geeky rival, Mandark, to try and save the planet. He turns his dad into part-man, part-arm wrestling machine; makes his mom become a super hero; and even creates a way to make a dog talk. Astounding!
