This reminds me of a funny story that I indirectly experienced over Skype (ah, the wonders of the future) with my friend while he was at Disneyland.
So he was at DCA, "streaming" the Play Parade over Skype while I was at home, and the parade ended. Suddenly one of the planters came alive with Mater's loop (the parade had been finished for a couple minutes by this point), Mater yelled "5-4-3-2-FUUUUU--" and it cut off.
We had a good laugh at how random and abrupt that was.
Considering it premiered immediately before DCA's retooling (and the construction that entailed), it made the parade feel like it ran for a lot shorter of a time than it actually did because of all the construction. Then it came back and people got tired of it pretty quickly, and here we are.
