Weirdest items ever left behind by guests?

We found head and torso of a shop dummy. We called him Hans and he stayed a few years in the hostel. He got his own Facebook page, and showed up on many photos of our guests on beaches, in hostel beds and some pretty funny locations. Unfortunately he dissappeared one winter during a renovation as our hostel owner and his construction workers didn't know about our V.I.P. guest. R.I.P. Hans!
