Pirates soup

Fishy as it may sound
Kills three birds with one stone
As mates are to be found
In the galley alone

Loaded with a rich stock
Serving more than just one
Strutting just like a cock
When it is on the run

Scurvy dogs need so much
Of fruits with what they need
Limes and lemons, they have such.
We rarely overfeed.

As many of you have heard
Man lives not by bread alone
You will eat crow mark my word
As you reap what you have sown
