CJ continually pulling faces, raising his eyebrows and generally looking pained when the other side gets the answer wrong shows his total lack of manners.
Why doesn't someone on the production side of the programme tell him it is bad manners and that it shows a totally unjustified measure of his own ability?
He is a pain all those facial expressions are annoying and unsportsman, litttle does he realise that himself and Judith are "lightweights" on Eggheads. And that hairstyle!! I don't think the production team want really good quizzers some of our local quiz teams would match them anytime.
The production team wouldn't want him to stop pulling faces, that is part of the entertainment. We have to dislike the Eggheads and like the challengers as they are the underdogs.
