During my four years of high school marching band Disneyland asked us to perform marching routines down Main Street. In all of those times we got to go "backstage". I say it in quotes because "backstage" is basically where you smell the stuff they try to keep out of the park, smell people smoking everywhere, see performers taking off their heads, and feel your dreams being crushed.
I saw Minnie Mouse take off her head. There was a man inside. He had a beard.
