What did I tell you? My head is a perfect circle with one radius in ALL directions!
Unfortunately, we found that vertically the radius was 8 in. but horizontally, it measured 7 in. Making your head an ellipse not a circle!
THAT CAN'T BE POSSIBLE! I've has a radius of 7 since I was born. I... I have to go.
And with that, "Circle Man" (Ellipse Man) fled. Ashamed of having, for the first time, two foci to draw the shape of his head, and not a center with one radius. And after he fled, no one ever heard from Ellipse Man again.
