My other favorite movie story was when we were seeing Gangs of New York here in DC.
This 80 year old guy was sitting in the row in front of us, and he turns around and starts cursing out the person sitting behind him, accusing them of kneeing his seat. Then later, a teenager (13?) in his row gets up to go to the bathroom. The 80 year old guy trips the teenager, who falls to the ground. The 80 year old yells at him, "AND DON'T COME BACK".
