Dexter's Lab is a Cartoon Network classic that ran for 4 seasons with a total of 78 episodes mostly twenty-two minutes long from 1996-2003 (initial run ended 1998, second run started 2001). I love this cartoon. I find it really funny (I'm 52). So do my 2 sons in their late teens. Dexter is a short, stocky, young, boy genius, with an Austrian accent, who uses his extraordinary intellect to solve all of life's problems with super-advanced technology. Something always thwarts his plans though. Usually it is his ditzy older sister, the perennially cheerful Dee Dee. Sometimes it is his arch nemesis Mandark. Yet, other times it is Dexter himself who gets in the way: he is thwarted by his own human nature or his innate animal nature. But alas, most of life's problems simply require a little human understanding which is not Dexter's forte. Season 1 - Disc 1 has more "Dial M for Monkey" episodes interspersed between the Dexter episodes where Disc 2 is has more "The Justice Friends" episodes.
