Animated sitcom]] The Grim Adventures of Billy & Mandy (also known as Billy & Mandy) is an American animated television series created by Maxwell Atoms for Cartoon Network, and is the 14th of the network's Cartoon Cartoons (albeit on when it was part of Grim & Evil, due to the Cartoon Cartoons brand being temporarily discontinued earlier in June 2003; the show itself is considered by some to still be a Cartoon Cartoon show regardless). 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.
