Trivia

 * This item may be a reference to the phrase "red herring".
 * This item may also be a reference to the scene in Monty Python and the Holy Grail in which the Knights who say "Ni" ask King Arthur to cut down the largest tree in the forest with a herring. Shortly afterward, Arthur says "It can't be done" and the knights are weakened when they hear the word "it".
