That reminds me of a bizarre story in Moscow a few years back. Most Russian high-rise apartment buildings have a trash chute in the stairwell, and they often get clogged. A maintenance person was once trying to fix one and reached down to far, and fell in. The chutes are very narrow, but I guess a thin person could fit. He was stuck between floors for several hours, and you can just imagine all tthe trash he was in. I think they had to cut the chute open to get him out.
