Once upon a time there was a local fisherman.
And every day he would set out on a small boat to catch fish to sell at the local market.
Until one day he got a phone call about a giant octopus sighting in the local area.
And because of this, all his attention went to finding the octopus
And because of this he wasn’t paying attention to his nets or the giant octopus trying to eat the fish in them.
Until finally the boat lurched and he turned around and realized he’d have to cut the net free or risk entangling the octopus in them.
And ever since that day he’s brought in an extra person with him to act as a lookout for any giant octopuses or other giant sea-life.
