I hate chat shows. Former chat show host Paul O'Grady -- famous for creating the comic drag character "Lily Savage" -- made an acute observation about the nature of such entertainments.
I felt I was part of the PR machine. There was so much interference. They’d want this guest or that guest. Every question had to go through the lawyers. I was just another plug for someone’s book or film.[From Paul O'Grady: Why did I give up the chat show? I couldn't stand the guests! | Mail Online]
This is why I don't watch chat shows, even Graham Norton who can be very funny on occasion. They should be banned from the BBC completely and only shown on ITV with an OFCOM warning that you are watching advertisements disguised as programmes.
