Mona Lisa, Mona Lisa, Leo made you,
But are you a lady with a mystic smile?
If art historians only could have scraped through,
They might find something under that pigment pile.

He was wily, renderer of Mona Lisa--
You can't tell if it's a smile, the way lips part.
Many schemes have been wrought about your rep.
Some are wry fare; some are sly fare.
For your form, you're revered, Mona Lisa.
Your mug is old but knowing. . .much loved work of art.

He was wily, renderer of Mona Lisa
In the way he made the face. . .how the lips part.
Many schemes have been wrought about your rep.
Some are wry fare; some are sly fare.
We've been warned, you'd reveal, Mona Lisa,
A somewhat old, unlovely Leo 'neath this art.

Mona Lisa, she or he, huh?
