Oh, a flounder's life is a wonderful life,
A-lurkin' under the sea,
I'd need no rehersal to be a demersal
It's the life of a flounder for me!
Oh, the life of a flounder for me!
Oh, a flounder's life is a wonderful life,
Your eyes are on top of your head,
For lying quite hidden, then pouncing unbidden
What a glorious life it would be!
Oh, what a glorious life it would be!
with apologies to pirates everywhere.
