One of the last good cartoons for Cartoon Network, created by Maxwell Atoms. It stars three main characters: Billy, a total moron who has an IQ of -17. Has a big red nose, a baseball cap, and a large fear of clowns. Mandy is an intelligent but very sadistic girl, and rarely shows any emotion other than anger and boredom. She can permanently scar someone just by looking at them. Grim, who is a skeleton that reaps souls, and got the job in middle school. He is around 137,000 years old, and speaks in a Jamaican accent. An interesting fact is that both Mandy and Grim lack noses, but Billy makes it up with his huge nose.

The plot starts at Billy's house, and Billy's hamster Mr. Snuggles has it's 12th birthday. The Grim Reaper then comes to reap the hamster's soul, but is surprised at the total lack of fear from both Billy and Mandy. Mandy then bets the hamster's soul. If they won a game of limbo against grim, they would be able to keep the soul, and Grim would have to be their best friend forever (literally). If Grim wins however, he takes it. They proceed in the game, and Mandy cheats by distracting Grim with the hamster as he's limboing. Grim is then stuck with being their best friend forever, and this is how the show starts.

It was originally a part of a two part mini series, Grim and Evil, where it was paired with a show called "Evil Con Carne". They both eventually split into two different shows. Evil Con Carne was unfairly canceled early, and the Grim Adventures of Billy and Mandy became a very popular show on the channel. Some Evil Con Carne characters even made cameo appearances in the show.

It was canceled in late 2007.
