One of RuneScape's Monty Python references is revealed if players use a herring (cooked or raw) with any tree in RuneScape (except the one outside the Draynor Village bank, in which the security guard is hiding. It will also not work with Spirit Trees). The text will say "This is not the mightiest tree in the forest", in reference to one of the lines in Monty Python and the Holy Grail. If used with the Grand Tree, the text replies "It can't be done!" in reference to another line in the movie.
