One day, a friend and I were at the Magic Kingdom during the closing hour and no one (literally no one) except us and the cast members were any where to be seen at Aventureland. So, with no lines and no wait times, we walked right into a boat at Jungle Cruise to get our very own unscripted tour of the attraction. It was the best Jungle Cruise I've ever been on because the cast member working our boat was just really, really awesome (not too mention she had an adorably cute energetic personality). Any way, when we got to the scene with Native Americans chanting, she told us to listen very carefully. They were chanting, "Disco sucks"! She explained that when they built the ride in the 70's, that was the time frame of the music wars between disco and rock. She also told us that the voice of the ghost host at the Haunted Mansion is the same person who does Tony the Tiger: "They'r great!"
