Thanks! I think I ought to rewatch the movie(s), because I combed all through my copy of the book and couldn't find ANYTHING.... then again, maybe my finding skills are rusty. It's been a long time since I've been to Wonderland.
I don't know if it was in the novel, but it was definitely included in the movie! The White Rabbit spoke about it after the Mad Hatter and the March Hare had destroyed his watch. ^-^
