When faced with an irrefutable point, start talking out of your ass and when your opponent attempts to call you out on it say "let me finish" and then when it's their turn to talk yell over them until the show goes to commercial.
Some Guy: Bill, last week on your show you said that Britney Spears was a ruthless whore, and yet you defend Sarah Palin's daughter
*Bill employs the Bill O'Reily Defense*
Bill: Well that is absolutely taking things out of context and these two things are in no way related to each other at all and I for one am appalled that you'd resort to such trivial things like taking what I said last week and relating it to what I am saying this week
Some Guy: well actually that's-
Bill O'Reily: let me finish. so you need to take a look in the mirror and stop making such wild claims like what you've just said.
Some Guy: What you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.
