QotD: If you were a pirate, how would you avoid laughing when saying "poop deck"?

(sing to: “I Am the Very Model of a Modern Major General”)

I am the merry model of a modern man piratical,
I’ve information pharmaceutical and base metallical,
I know the kings of commerce and I quote their fighting tactical,
From Amex and Dow Jones my wealth is purely statistatical.
While very well acquainted too with matters catechetical,
My understanding soars when faced with humorous grammatical.
About stern superstructure of a ship embarking on a cruise,
I give you cheerful facts to curtail tendencies to misamuse.

I’m very good at keeping my full viscera from volvulus,
I know the scientific names of creatures coprophilious,
In short, in matters snickering about the excrementical,
I am the merry model of a modern man piratical.

I know our mythic history, King Arthur's and Sir Caradoc's,
Is found replete with sounds and songs to satisfy the gigglebox
I quote in elegiacs all the stories of the urinous
And find it still peculiar that it always stirs up such a fuss.
I can tell all fecal jests with straight-faced and undoubted ease,
I know the sacred lore concerning gaseous and fetid breeze,
Then I can hum a fugue of deck beyond amidships topping stern,
Reveal the nomenclature of poop deck before we must adjourn.

From lowest tar to captain sleeping snugly on the quarterdeck,
Our imbibition and ingestion force us all to make the trek.
In short, to keep one’s shipmates all from losing their good humorous,
One hangs one’s bottom off the top and sheds his own malodorous.

This placid vocalizing of the word in question comes at cost
My giggle at a victim’s farting gave him opportune riposte
So now, in matters snickering about the excrementical,
I am the merry model of a modern man piratical.

Thanks, Gil and Sully…
