I'm sure most people think the fish was put up there by a human. Not so. And no, it wasn't from being blown out of the water by dynamite and accidentally landing on that spear like weathervane like you may also assume. That fish crawled up there and impaled itself on purpose after a messy divorce. Then in 68 they added the directional north, south, west, east bars on there. The guy that did that was going to take the fish off of the spear but then he thought "No, I hate you." and left it there. I almost forgot to tell about the part where the guy wagged his finger at the fish too.
