Hulk (2003)
Approximately 1hr 46min into the movie the hulk is apparently in the sewers of San Francisco, fucking up the streets above. The pavement cracks and buckles. A trolley full of passengers derails, causing subsequent accidents. An old woman slams into the trolley, then someone slams into the back of her car. The person that slammed into the old lady's car caused her to jerk forward. And for whatever reason, seeing that old woman get hit by the other car made me laugh my ass off when I first saw it in the theater. I just watched it again before posting this and it still strikes me as funny. Not quite as funny as it was when I originally saw it. It's only about 1 second worth of film that I'm describing. Maybe I hate old people or I'm just an asshole.
If you're so inclined to check it out, heres a link to watch it free online.
