That reminds me, ever watch Family Guy with Peter worrying about his fatness? He formed a Fatness Group and all the fat people did were eat and constantly fart. In American Dad there were two occasions and the first one where Stan gets paranoid and starts going from normal to pencil thin. The Second occasion is when a Squirrel over eats cookies and just dies from a heart attack The tree house later gets burnt by the squirrel kids in a respectable honor.
