Reaching back to the olden days of Ralph Bakshi's version... I went with a group of fan friends to see it when it opened in town, and all of us heard the same thing when Gandalf was trying to open the gates of Moria:
"Egg roll! EGG roll!!!"
Needless to say, we went out for Chinese food after the movie.
And maybe if they'd brought Gimli's ox instead of Bill, they wouldn't have had any problem plowing down the doors.
