The Lab Rat

Dexter's Laboratory is an American animated television series created by Genndy Tartakovsky for Cartoon Network. Initially debuting in 1995 as a series of shorts on World Premiere Toons, the show was picked up the following year for its own series, broadcasting 78 total episodes and a television movie across 4 seasons. The second season finale, "Last But Not Beast", was originally supposed to end the series in 1998, but the series' production picked up again in 2001 with most of the crew being replaced. The third season episode "Copping an Aptitude/A Failed Lab Experiment/The Grand-Daddy of All Inventions" is the last episode of the series to feature Christine Cavanaugh as the voice of Dexter; from the next episode onward, Dexter is voiced by Candi Milo. The last episode aired on November 20, 2003. Also released was a controversial unaired episode called "Rude Removal", which was originally only shown at certain comic conventions. The segment was later picked up by Adult Swim and released to the public on January 22, 2013, online.
