The first thing that went wrong, according to Fat, had to do with the radio. Listening to it one night- he had not been able to sleep for a long time- he heard the radio saying hideous words, sentences which it could not be saying. Beth, being asleep, missed that. So that could have been Fat's mind breaking down; by then his psyche was disintegrating at a terrible velocity.
Mental illness is not funny.
