Draw Me a Circle

Draw me a circle that's perfectly round
One curving line, simple and fine
Now add two ears, and a lopsided nose,
And if you care, add some hair
Now draw two eyes and make them bright
Because they've just seen a beautiful sight
Sketch in a mouth with a radiant grin
One coming deep from within
You've drawn me a circle and now that you're through,
It's a picture of me after being with you...
