-- On WABC Radio's Rush Limbaugh and his oxycontin problem: ''Do you know how much drugs you have to take to go deaf?''

-- On losing the Emmy two years in a row to American songbook stylists Barry Manilow and Tony Bennett: ''My real enemy is the Great American Songbook. I'm most upset at Ira Gershwin and Irving Berlin.''

-- On his lacerating 2006 White House Correspondents' Dinner roast of George W. Bush: ''(The President said afterwards) 'well done.'''
