I'm Seeing Spots! (Polka Dot Panties)
 

There's nothing wrong with your vision, these ladies are wearing spots!

The area of a circle is pi*r squared. The area I'm interested in is under these circles.

The tangent line through a point P on the circle is perpendicular to the diameter passing through P.

I have no idea what that means. But pussy begins with a P.

Pi is an irrational constant. Some of us constantly look for a different kind of pie.
