The Grim Adventures of Billy & Mandy

In The Grim Adventures of Billy and Mandy, we meet the idiot named Billy and the snotty girl named Mandy, who apparently win a bet with the Grim Reaper over a sick hamster, making him have to be their best friend forever! These adventures show how much they drive him crazy! This show started out as Grim & Evil which combined "The Grim Adventures of Billy and Mandy" and "Evil Con Carne".
