You didn't believe it when Andrew Bolt told you. You didn't believe it when puzzle maker Christopher Monckton told you. So will you finally believe it when prime minister Kevin Rudd tells you?
"Let me tell you, (global warming) is all one global communist conspiracy. So watch out, and lock up your friends. It's going to come and get you in the middle of the night."
An interesting strategy. That line got Rudd one of his biggest, and most genuine, laughs of the night from the Q & A audience of students, and successfully deflated some of the tension of the room.
