Ryan Seacrest was talking about William Hung on the radio and he said William Hung honest to God does not know that he sucks. He thought William Hung was in on the joke and that he was just there to cash in on it but he said he spoke with him at Wango Tango which changed his mind.
William Hung was surprised at the turnout and he said something along the lines of "I can't believe I am able to fill these seats with my fans. If I improve my singing, I can fill more seats ..." something like that.
Everyone's in on the joke but him.
