FW: What not to do during Return of the King

1. Stand up halfway through the movie and yell loudly, "Wait... where
the hell is Harry Potter?"

2. Block the entrance to the theater while screaming: "YOU SHALL NOT
PASS!" - After the movie, say "Lucas could have done it better."

3. Play a drinking game where you have to take a sip every time
someone says: "The Ring."

4. Point and laugh whenever someone dies.

5. Ask everyone around you if they think Gandalf went to Hogwarts.

6. Finish off every one of Elrond's lines with "Mr. Anderson."

7. When Aragorn is crowned king, stand up and at the top of your
lungs sing, "And I did it.... MY way...!"

8. Talk like Gollum all through the movie. At the end, bite off
someone's finger and fall down the stairs.

9. Dress up as old ladies and reenact "The Battle of Helms Deep"
Monty Python style.

10. When Denethor lights the fire, shout "Barbecue!"

11. In TTT when the Ents decide to march to war, stand up and
shout "RUN FOREST, RUN!"

12. Every time someone kills an Orc, yell: "That's what I'm Tolkien
about!" See how long it takes before you get kicked out of the
theatre.

13. During a wide shot of a battle, inquire, "Where's Waldo?"

14. Talk loudly about how you heard that there is a single frame of a
nude Elf hidden somewhere in the movie.

15. Start an Orc sing-a-long.

16. Come to the premiere dressed as Frankenfurter and wander around
looking terribly confused.

17. When they go in the paths of the dead, wait for tense moment and
shout, "I see dead people!"

18. Imitate what you think a conversation between Gollum, Dobby and
Yoda would be like.

19. Release a jar of daddy-long-legs into the theater during the
Shelob scene.

20. Wonder out loud if Aragorn is going to run for governor of
California.

21. When Shelob comes on, exclaim, "Man! Charlotte's really let
herself go!"
