So let me get this straight...
A mention of sailor in inebriated state is not acceptable for a nursery rhyme, but instead a bad-tempered
pirate is acceptable?
They leave a sailor - which is a very honorable profession in the end of the day - on the shore and replace him with a
pirate? A person whose profession mainly consists of plundering, pillaging and ravaging (aside from sailing)?
What insanity motivates these people I shall probably never find out, and that's likely a good thing...

EDIT:
It's not even a nursery rhyme to begin with. It's a sea shanty.
