I guess I'm a geek because I was amused reading this list of things not to do in the theater during "The Return of the King". (Props to Mark Shea)....here are a few of my favorites:
* Finish off every one of Elrond's lines with "Mr. Anderson."
* Imitate what you think a conversation between Gollum and Dobby and Yoda would be like.
* Dress up as old ladies and reenact "The Battle of Helms Deep" Monty Python style.
