John Dory's - Fish, Grill, Sushi

This a story of old John Dory,
albeit a fisherman's tale.
It's the honest truth,
so by my tooth,
about how he saved a whale.
He was casting his line into the sea,
Some time from two to a quarter-to-three,
When he heard a great noise,
and felt a big splash,
An unnatural swell,
and a heck of a crash.

And when he looked down,
he saw a big whale with a mooring rope
wrapped round his tail.
He took a deep breath and held it in,
He waited not, he dove right in,
For 20 minutes he didn't come up,
he swam with all his might
Till the whale was free to splash his tail ...
and swim off into the night.
