Dexter and Computress Get Mandark!

"Dexter and Computress Get Mandark!" is an episode from season 2 of "Dexter's Laboratory". It is the result of a contest held on the Cartoon Network for young viewers to write and submit a story for the series. The winner of the contest was six-year-old Tyler Samuel Lee, who also narrated the story, and did the voice impersonation of Dexter and Mandark. (His mother also helped him out at times. Usually the cartoon lady popping out of nowhere during the scenes). The episode was also based on pictures the child drew, which director John McIntyre made into the storyboard, and the final animation. It first aired, Wednesday April 29, 1998 on Cartoon Network.

Plot

Mandark kicks out his computer who is also his brother, Computress, who then goes and works with Dexter in order to get even. Dexter invents a shrink/grow ray, and aims to shrink Mandark's head; but Computress accidentally throws the switch to grow, and Mandark's head expands to the size of the universe, and then bursts into millions of tiny heads. Dexter now sends the yet again rejected Computress away, saying (in the little boy's imitation of him) "you are stuupid; you are stuupid, and don't forget, you are stuupid".
