Curious

Have you ever seen previews for an episode of a TV show and then watched the episode to find a scene that was in the preview not in the episode? Then watch the preview for the next episode only to find the scene is actually in the next episode.

I was watching Burn Notice tonight and there was a scene in the preview for this episode, but it wasn't in the episode. At the end of the episode the scene was in the preview for next week's episode.
