Dexter's Laboratory is an animated series which was produced Hanna-Barbera Cartoons for Cartoon Network from 1996 to 2003. The show was a big hit in its day and retains a timeless appeal and now, it's finally available to own on a complete 12-disc DVD set containing every episode.
The series involves a boy genius named Dexter, who has a secret laboratory filled with highly advanced equipment, hidden behind a bookshelf in his bedroom. Access to this never-ending laboratory is achieved by saying various passwords or by activating hidden switches on the bookcase.
Dexter is almost always in conflict with his ditzy older sister, Dee Dee, who delights in playing in her brother's lab, often destroying his inventions and creations. He is constantly keeping the lab a secret from his clueless, cheerful parents, and (in the beginning of the show), Dee Dee is the only other character to know about his lab.
The show's humor derives in part from Dexter's essentially one-sided and intense rivalry with his sister (in which Dexter, although brilliant, never gets the upper hand) and from exaggerated stereotyping of his high intelligence and social awkwardness. A lot of absurdist and surrealist humour is used as well. Dexter also speaks with a Polish accent while his parents speak with distinctive American accents.
Also features all of the 'The Justice Friends' and 'Dial M For Monkey' shorts which featured in the series
