https://www.youtube.com/watch?v=z8mn3nLPSMY It is absolutely no surprise that Robin Williams won an Oscar for his performance in this film. Did you know that he improvised this scene about his wife farting in bed? Matt Damon had no idea it was coming, so that laughter is completely genuine. You'll also notice that the camera shakes slightly, because apparently the cameraman couldn't stop himself from laughing either. Have we forgotten any?
