The Grim Adventures of Billy & Mandy

On-screen title card in Hanna-Barbera's hands.

Final version.

The Grim Adventures of Billy & Mandy, or simply Billy & Mandy, is an American supernatural black comedy created by Maxwell Atoms for Cartoon Network. The pilot, "Meet the Reaper," was produced by Hanna-Barbera and aired on June 9, 2000, although the studio crumbled into dust when co-founder William Hanna died, and Cartoon Network Studios took the reigns. The series proper began on August 24, 2001, and ended on November 9, 2007, with 77 episodes across six seasons. During this time, there were also two TV movies, and a post-series spin-off movie, Underfist: Halloween Bash, in 2008.

The series is about an idiot, happy-go-lucky boy called Billy, his best friend, the cynical and coldhearted Mandy, and a Jamaican-accented Grim Reaper, who they tricked into being their friend for eternity.

Due to starting out as Hanna-Barbera cartoon, as well as airing on a channel that claimed its fame on Hanna-Barbera reruns, as well as new series from the studio, Billy & Mandy makes several references and even guest appearances from Hanna-Barbera's properties.

• "Modern Primitives:" Fred Flintstone is found in a block of ice by Billy, who thinks he can keep Fred as a pet named Jack Steele.

Scooby-Doo

• "Reap Walking:" When Gladys says "I would've gotten away with it, too, if it weren't for those meddling kids," referring to her own son, Billy, and Mandy, although the screen switches to Mystery Incorporated. Mandy corrects the camera by saying, "No, no, no, down here."
