I've heard of quite a few last day pranks performed by Jungle Cruise skippers. This one is quite hilarious and worth the laughter. It seems to have been pulled off right enough to the point of it seeming really a part of the show. That kind of humor is what makes Disney theme park entertainment usually so memorable. You don't remember the Country Bears for the slow songs and love songs. You remember it for the more humorous moments, such as Big Al, Liver Lips, and the three trophy heads.
That was Trevor, He and another former Jungle Cruise Skipper have a podcast together called "Joey and Trevor Talk To Eachother". It's a pretty funny podcast and they sometimes share stories of their JC days. Another good podcast that they're sometimes on is "Tales From The Jungle Crews", a podcast that is hosted by an ex skipper named Kyle and he has different skippers on his show and they tell stories of their time working in the jungle. Good stuff!!!
