Monster Catfish
Fish like this really do exist, so why would they ever get right into the water with it? This thing could feed those guys for weeks unless they decided to let it swim away. If so, hopefully, it didn't eat them first.
Classic Jokester
See? Even the most sophisticated setups don't guarantee that you catch a fish every time. This guy slid right between both of those poles and safely got away. Better luck next time!
