Dilbert: I invented a device that can help people lose weight. Boss: I wouldn't need that because I have willpower. Dilbert: Then why are you overweight? Boss: This is temporary. Dilbert: You've looked exactly the same for years. Boss: I can lose this weight any time I want. Dilbert: So... are you saying you choose to be less healthy than you could be? Boss: I'm saying I'd rather be happy than healthy. Dilbert: Are you happy? Boss: No, because I'm hungry. Dilbert: And eating will make you happy? Boss: Well, I usually eat until I'm sick.
