We call her monkey, because she has hair that makes her look like a monkey.

 I changed the words of Yankee Doodle
to sing to Sloan, but I always got stuck after "Monkey Doodle went to town, riding on a banana..." Then last night TJ solved the rhyming conundrum, like some sort of poet. I am remiss I didn't come up with it. It is beautiful in its simplicity.

Monkey Doodle went to town

riding on a pony

stuck a banana in his pants

and called it a big boney.
