Is the German guy part of the show?

This is the sound of an orchestrion, one of those cleverly-named self-playing musical instruments at the Siegfried Museum. When I first heard it, I just thought it was weird, then realized it was a meld of at least four sounds: the orchestrion, a mechanical bird chirping insanely, someone ringing an obnoxious bell, and a guy yelling loudly in German. (Did anyone ever yell softly in German?) I was a little disappointed the orchestrion didn't have a "guy yelling loudly in German" setting. But it could have. Who knows.

(Post-blog observations. Watching this thing a little more closely, I notice something going on that reminds me of the Beer Hall Putsch. The place is stuffed with Germans, most of them having some sort of Oktoberfest celebration with beer and bratwurst. If you look carefully on the left, there is a man wearing a military beret. Something odd going on here. And why on earth does this Orgasmatron or whatever-it-is have a big mirror on the front of it? You could take selfies that way, of course, in the good old-fashioned way.)
