At the end of the movie Twister, there is a huge storm. The tornado is getting closer and closer, and things are flying through the air and trees are being ripped out of the ground etc. Well, if you look carefully during a few frames of this scene, the wind is blowing crazily enough to make trees go flying across the sky...but funnily enough the trees in the background aren't moving at all.. not even swaying in the wind. Perfectly still.. I wonder if they paid them to do that.
