Good Will Hunting 

Robin Williams is a comedic legend, and what’s even more impressive is his amazing acting in the serious roles that he took in his career. His portrayal as Will’s therapist Dr. Sean Maguire in Good Will Hunting, earned him an Oscar. 

During one of Sean and Will’s sessions, Williams was supposed to tell a story about how his deceased wife would turn off the alarm, but instead he improvised a story about she used to pass gas in her sleep, and that it was so loud sometimes it woke the dog up. Damon’s (and the cameraman’s) laughs are completely genuine, and it’s one of the most memorable scenes in the hit movie.
