Every time someone says witch you must yell Burn her, burn her!
Prop alert: Bring ten whole Florida coconuts, each with a tiny swallow drawn on top with a Sharpie. For each squire that dies in the movie, you must throw one coconut at the screen.
Costumes are encouraged. You may show up dressed as Sir Arthur, Robin, Galahad, Lancelot, or the Black Knight. You may not, however, show up dressed as a Sir Not-Appearing-In-This-Film.
Whenever the word Ni is uttered, you and your friends must exclaim, A shrubbery! The person who says shrubbery last is no longer a Knight of Ni, and is henceforth required to say Ekki-ekki-ekki-ekki-ptang, zoom-boing, z'nourrrwringmm.
More props: Four packets of fake blood, to be ejected onto the closest person for each limb severed from the Black Knight.
Props, addendum: Wet naps, for the removal of fake blood.
Finally, when the theater ushers come to eject you, you must grab your friends and yell in unison, Run away!
