In Uruguay, I was once on a very crowded bus when this rather creepy looking man got on and began pushing his way down the aisle, announcing loudly, "CAREFUL! CAREFUL! There's an alligator in this box! It'll bite your hand off!" These declarations continued as he moved towards the back of the bus. In his hands he held a poorly taped up cardboard box. People cleared for him. He sat down only a seat behind and to the side of me, and I was privileged to listen as he expounded on the dangers of his toothed friend to his lucky neighbor for the entire trip.
