Paying to not see a movie?

So I was watching the Pink Panther 2 the other night (steve martin was hilarious but plot was pretty week), when i heard someone behind me on the escalator say, "My favorite part of watching a movie is seeing the previews!  Sometimes I even forget what movie I'm watching cause the previews are sooo interesting..."

Has that ever happened to anyone?  I know its happened to me a bunch of times.  I get so involved in the previews that sometimes I'm kinda sad that their over.  Yet when I go to see one of the movies that was in the previews, I still get sad cause the new previews are over....
