Long John Silver's - Alaskan Flounder - Big Catch
Summary: Fishermen unload a catch of square fish
Three fishermen pull a catch of fish on board. One fisherman looks at the fish, repulsed and says "that ain't natural." Another fisherman explains that the square fish are fish patties and fit well inside of a bun. He then asks the captain what he's eating. He tells the men that it's Alaskan flounder and the best thing about it is that it's not the square fish they just caught.
