Nativity Wars

I bought a small nativity scene during my visit to Germany a couple of years ago.  It sits on the ledge that separates the kitchen from the living room.  Unfortunately, that nativity has become the family battle ground.  Here is my evidence . . . Apparently, some members of my family believe there is a right and wrong way to display this scene.  Every five minutes, I'll hear a disgusted sigh and it has been moved again.

I don't really care which way it goes, I just want to know who put the fingerprints on it!
