I don't mind people putting us down, because if everybody really liked us, it would be a bore. You've got to have people putting you down. It doesn't give any edge to it if everybody just falls flat on their face saying, "You're great." We enjoy some of the criticisms as well, they're quite funny; some of the clever criticisms, not the ones that don't know anything, but some of the clever ones are quite fun.
