Tonight, my family and I decided to watch the Disneyland Tenth Anniversary Special on the "Your Host, Walt Disney" DVD. We were enjoying the festivities, commenting on how different entertainment was in 1965. At one point, there is a dance in front of the castle with Mary Poppins and the Chimney Sweeps. Various Disney charachters are dancing in the background, both adding and at times distracting from the foreground action. Directly behind Mary and the Sweeps are the Seven Dwarfs. This is where it gets interesting! At the end of the dance, Mary takes off with her umbrella to the right of the screen. Apparently, the head of one of the dwarfs got caught in the flying mechanism. You can see, off to the right, his fake head get lifted off, and then fall to the ground in front of him, exposing the actors real head! We watched it several times in disbelief... yes, it is actually there! I laughed so much I thought I would die! If you own this DVD, take a look and let me know what you think :-)
