Toon is a role playing game by Steve Jackson Games wherin you create a cartoon character and essentially play with effects based in classic cartoons with emphasis on the Warner/MGM style of the mid-20th century. It emphasizes slapstick, silly effects, and cartoon physics. There is no death to speak of, since most things that would kill you usually end up generating a comic effect.
There is a particularly grim and dark adventure that was written for Toon by some guy in the mid 90's, based on Who Framed Roger Rabbit. It's the ultimate in black comedy roleplaying.
