Grim adventures is one of my all time favourite cartoons. The plot is basically 2 kids, a dim witted boy named Billy and his creepy, scary friend? named Mandy who trick the Grim reaper himself to spend eternity playing with them. They get up to insane and hilarious antics featuring dangerous creatures and items from the underworld. There are many entertaining characters featuring the nerd and Billy's best friend Irwin, Billy's idiot father and his strange mother, Mindy the spoiled rival to Mandy, the former villain general Starr, supposed son of billy Jeff the spider and exterminator Hoss Delgado. Oh yeah lets not forget the creepy scene after the intro consisting of Mandy saying something threatening. It is not enough to succeed, others must fail.
