- Karl Pilkington: I don't think smiling makes other people smile. If you're a little bit pissed off and someone's walking around with a big smile on, it can annoy you more. You'd go "why are they so happy? why aren't I that happy?" So you're better off knocking it about with a right load of miserable bastards. And then you go "God, my life's not that bad. these lot are miserable".
