People are dragging this scene from Billy Madison up practically every time Donald Trump makes an appearance on TV. But, I reckon that it’s worth memorising for any situation in which you have to listen to an ill-considered opinion!
“Mr. Madison, 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.”
