The Grim Adventures of Billy and Mandy is an animated series from Cartoon Network. It was created by Maxwell Atoms and it premiered in August 2001. The Show follows two friends, the happy-go-lucky Billy and the sour unhappy Mandy, who befriend the Grim Reaper, who simply goes by Grim. The kids bet Grim in a limbo game to keep their sick hamster and for him to become their best friend forever and they won. Since then, they have been good for nothing pests and messing with the unnatural things of the underworld and Grim’s world. This always means trouble! This show started off alongside with Atom’s other show Evil Con Carne in a show called Grim and Evil, and they’ve been together two years maximum. But in 2003, they became separate shows. Evil was canceled in early 2005, while the Grim Adventures of Billy and Mandy is still going and still is making episodes.
