In Dustin Hoffman and Anne Bancroft's first encounter in the hotel room (a scene from The Graduate), Anne did not know that Dustin was going to grab her breast. Dustin decided offscreen to do it, because it reminded him of schoolboys trying to nonchalantly grab girls' breasts in the hall by pretending to put their jackets on. When he did it onscreen, director Mike Nichols began laughing loudly offscreen. Dustin began to laugh as well, so rather than stop the scene, he turned away from the camera and walked to the wall. Dustin banged his head on the wall, trying to stop laughing, and Nichols thought it was so funny, he left it in.
