The current repeat on BBC2 of House of Games - only heard of one of the four "celebrities".
There's a game I play if, and it's a big if, I see the start of one of those celebrity quiz programmes. It goes "who the foxtrot are you?" or "can't stand him/her". There's a good chance there's no one of interest, so I don't watch. You can tell that I do a lot of channel surfing these days trying to find something to view.
So called comedians seem to be cleverer than presenters from news. Sports "stars" and those whose celebrity status is connected to webshites are the thickest.
