From an interview with many gems, the following is my favorite:

60 Minutes' Pelley: "You know that there's a perception in some quarters of the country that you're stubborn."

Bush: "Oh, yeah. Well."

Asked if agrees with that, the president asks, "Do I agree that I’m stubborn or do I agree that people think I’m stubborn?"

Pelley: "People think you do. What do you think?"

Bush: "I think I’m a flexible, open-minded person. I really do. I really do."

Hold on (slapping knee), I'll be with you in a second (can't breathe, laughing too hard).... (falling off chair)....
