The best one I did was a spoof remix of "Charlie the Unicorn: Chamber of Horrors", starring Mario as both of the unicorns, Luigi as the Weasle, and Peach as Charlie XD
The scene was shot at Bowser's old Super Mario Bros. Castle.
I don't even know if I've uploaded it to Hantena yet. Buts it's funny as hell.
I know my apprehensions might never be allayed. And so I close, realizing that perhaps the ending has not yet been written...
