What would be wrong with shouting out "And the American Way" at the point in the movie where the PC Lefty proto-Alzheimers writers (no memory of anything) left it out?
Ya know if a lot of people did that, I don't think any theater manager would try to eject anyone because the publicity would be horifying. Plus a manager trying to do that (kick someone out) would have to face many allies of the person who said it. Confligration at the multiplex?
