It follows two children named Billy--a slow - witted happy - go - lucky boy--and Mandy--his dark and cynical best friend--who, after winning a limbo game to save Billy's pet hamster, gain the mighty Grim Reaper as their best friend in eternal servitude and slavery . </P> <P> Billy & Mandy began as a series of segments on Grim & Evil, from which it was spun - off, along with Evil Con Carne, on August 24, 2001 . The show ran as a separate series from June 13, 2003 to November 9, 2007, but a telefilm, titled Underfist: Halloween Bash, aired on October 12, 2008, officially bringing the series to a close . In addition to the episodes, three movies, two special episodes, and nineteen shorts were made, with 3 award wins for the series as a whole . Billy & Mandy has also been made into a video game as well as various licensed merchandise . After the series ended on Cartoon Network, reruns currently aired on Boomerang from time to time . </P> <P> The series is centered around the exploits of Billy (voiced by Richard Steven Horvitz), a dimwitted and happy - go - lucky boy; Mandy (Grey DeLisle), a cynical and merciless girl, and Grim (Greg Eagles), the Grim Reaper who is often tormented by the duo . After cheating at a limbo match against Grim (in retaliation for putting the limbo rod too low for them to go under), he is enslaved in a permanently unwanted friendship with the children . Grim is miserable in the first days of his servitude, and even fantasizes about killing them multiple times . However, as the time passes, he gradually adapts to the new life, and even grows to care for Billy and Mandy, if only somewhat . Despite this, he retains a love - hate relationship with the two and desires to eventually break free from his servitude . </P>
