Oh my gosh, this story is crazy.
Apparently a burly guest on his first visit to Disneyland recently actually pulled the sword from the stone in front of King Arthur's Carousel. The girl he was with told him that there would be a prize if he could, so he really went for it. The sword broke off and he raised the jagged blade right our of its anvil.
Personally, I think there totally should have been a prize.
