Bill: All in all, another week in America. God help us.
Bill: Public misbehavior by the famous is a powerful teaching tool.
Bill: Yeah, I'm obnoxious, yeah, I cut people off, yeah, I'm rude. You know why? Because you're busy.
Bill: Other interview news shows are guest-driven. The O'Reilly Factor is driven by me. I will not stand for 'spin.' I look for guests who will stand up and verbally battle for what they believe in.
Bill: Evil cannot be "treated" -- nor should it be. Evil has to [be] confronted and destroyed and it matters not why the evil is in play. Society has no obligation to try to rehabilitate evil.
Bill: If you have good friends keep them. If you don't have good friends, get them. True friendship, a rare gift, is never taken lightly. Your friends will tell you the truth about yourself, and not charge you $200 an hour. They will tell you the truth but they will stick by you when the rest of the world turns away.
