I suppose the the thing is that most people on meeting someone they don't like the look or sound of, avoid them.

Well these people can't - not if they want to be on telly. So they devise strategies. Sometimes of quite mind blowing evil, sometimes betrayed by remarks of casual nastiness. And thus they deal with the situation. Or so they think, but the camera captures everything.

There are levels to this game. Its a cross between the bearpit and the chess game. The cruel and and mocking tones of the presenters is an inherent part.

It wouldn't be my choice of TV, but my wife loves it so I get sucked in every year, and before long I know all the people - whether I want to, or not.
