Graham Norton can dish it out but he can't take it.
I was a huge fan of his until he started to ridicule Jade's looks, Tim's hair, Alex's parents' appearance and so on. Right now, I am very tired of his attempts at humour and think he had a heck of a nerve to show up as Jade's 'celebrity supporter' after all the abuse he had given her during BB.
If I were Tim or Jade, I would have ignored him or thrown a drink over him, but not wasted any time trying to talk to him. You would only end up being ridiculed on his show anyway, no matter what you had said to him.
