My boyfriend went to sea-sea-sea
And all that he could see-see-see
Was the bottom of the deep blue
Sea-sea-sea

In succeeding verses, the "c-c-c" part was replaced with other, nonsensical, terms. I recall "ooo-watch-ee-wah."

In this one, the term "long-legged" is varied, and the hand position changes to depict the pertinent physical attribute:

Did you ever, ever, ever
In your long-legged life
See a long-legged lover
And his long-legged wife?

No, I never, never, never
In my long-legged life
Saw a long-legged lover
And his long-legged wife


Long-legged becomes, in succession, short-legged, knock kneed, and bow-legged.
