You can find this freshly posted as of yesterday. ‘She should be ashamed of what she did to Sarah Palin,’ which I think is a discredit to both me and former Governor Palin. She’s not fragile. And I’m not mean. And to imply otherwise is a disservice to us both. No one ever said, ‘Oh that Will Ferrell. He should be ashamed of the way he’s conducting himself playing George W. Bush.’ No one would ever say that.
