“He's gone... Beyond nutty. Beyond wacky. Beyond zany!”
Warren Nefron is a hopeless klutz who has some of the worst luck in the world: when he tries to end it all with a foolproof suicide plan, he still manages to mess it up. In desperation, he goes to a psychiatrist to see if there is some way for him to end his troubles.
