Exactly – you said "often" ('frequently') only once. - W. S. Gilbert

Now landsmen all, whoever you may be,
If you want to rise to the top of the tree,
If your soul isn't fettered to an office stool,
Be careful to be guided by this golden rule—
Stick close to your desks and never go to sea,
And you all may be Rulers of the Queen's Navee.

When I was a lad I served a term
As office boy to an attorney's firm.
I cleaned the wndows and I swept the floor,
And I polished up the handle of the big front door.
I polished up that handle so carefullee
That now I am the Ruler of the Queen's Navee!

Oh, I am a cook and a captain bold
And the mate of the Nancy brig,
And a bo'sun tight and a midshipmite
And the crew of the captain's gig.
