I've been trying to remember where I saw this scene: A martial arts teacher and a group of his students are inside a one-room building. The students are sitting around the edge of the room, and the teacher is standing in the middle of the room next to a boulder. To demonstrate his skill, he delivers a karate chop to the boulder, but nothing happens. Then he calmly leaves the room, and as soon as he's gone, the students start laughing. Then the scene cuts to a shot of the teacher outside, walking away as the whole building collapses behind him.
