My daughter and I caught the show just last week (Feb 16th) where two adults tried to pull the sword then a girl pulled it most of the way out. She became something-something of Fantasyland for the day. It was a pretty cute show; happened about 11:30 am.
I actually kinda prefer it without the show. Even though not as many people get to experience it, the occasion becomes more "magic" and I would think it makes it more special not only for the kid but for the parents as well.
