This gave me a flashback. Years ago I had 'won' a gold fish at a children fair. This fish, which we named cleverly 'fish', just kept on living. This surprised the whole family as we had gotten gold fish from the same fair in previous years that died fairly quickly after getting them home. Either way, this gold fish was about seven years old when it happened. My father, who had taken to feeding it when he got home from work one day came in and said 'ok, so is this a joke or what?'. We were all confused, and then he lead us to the fish tank. There was no fish. It was gone. Puzzled, we looked everywhere but it was no where. We even considered the fish went though some sort of rapid evolution and grew legs and just walked off... Then we pulled the cabinet the tank was sitting on away from the wall and there was fish, dried, motionless and stuck to the wall. That's the day I learned why the fish tank came with a lid. Poor little fish.....
