Cover art for Colleen lyrics by Joanna Newsom

I know the "He-Who-Easily-Can-Curve-Himself-Against-The-Sky" being a reference to the narwhal-woman story has been pointed out... But... Narwhal horns are pretty phallic. And I don't think anyone has touched on it being a dirty joke or an attempt at flirting. Would provide evidence for the sea being symbolic of a place of unrestrained sexuality or lack of restraints in general, as well. Just throwing that in there.

I agree with this, and elaborated further on it in my comment.
