Bobpursley is one of the Jiskha experts.
I be a Sailor.
All my bloomin' life.
Me mother was a mermaid.
Me father was King Neptune.
I was born on the crest of a wave
And rock the cradle of the deep.
Seaweed and barnacles are me clothes,
The hair on me head is hemp,
Every bone in me body's a spar,
And when I spit, I spit tar.
I'se hard, I is, I am, I are.
