"The Grim Adventures of Billy and Mandy," by Maxwell Atoms, was voted the new cartoon viewers would most like to see made into a series in the Cartoon Network's first Big Pick Contest in August 2000. "Evil Con Carne" was another short Atoms did as a Premiere Premiere Cartoon on Cartoon Cartoon Fridays. So "Grim and Evil" is actually two shows in one: each individual program has either two episodes of Grim and one of Evil, or two of Evil and one of Grim.

"Grim" refers to the Grim Reaper. Having lost a bet to two little kids -- goofy, sweet-natured Billy and sharp-witted, unsmiling Mandy -- Grim is now stuck being their best friend forever, thanks to a rash statement he made when he thought winning was a sure thing.

"Evil Con Carne" is the story of Hector Con Carne. Once a mega-rich playboy weapons smuggler, Con Carne's body exploded in an assassination attempt by the world-famous warrior, Cod Commando, after which Con Carne's brain and stomach were rescued by a mad scientist. He is now trying to rule the world with his two remaining organs housed in the body of a particularly dense ex-circus bear named Boskov. Con Carne commands a small and incompetent army from a bunny-shaped fortress on an island called (what else) Bunny Island.

Episode 13, first broadcast October 18, 2002, was the final "Grim and Evil" episode. When the next season started on June 13, 2003, most of the remaining Hector Con Carne episodes had been removed from the Grim Adventures episodes and were put into a show of their own, which came to an end when they ran out of already-made episodes. Grim Adventures, however, is still going strong. Check out the official Grim Adventures of Billy and Mandy website.
