I thought it was silly to even argue. When I was a little kid, I thought the diameter of a circle was the natural way to measure it. When I understood enough to realize the radius made more sense, of course you'd use the ratio of the circumference to the radius.

Later on, I understood even more, and realized e was better than both of them anyway. (Well, e^x. e is to e^x as pi is to 2*pi).

Unfortunately, I started memorizing digits when I was a little kid, so now I have 67 digits of an ugly number memorized. Also, I found out memorizing digits is ugly anyway.

If you want to memorize something pretty, try Sum(x^k/k!)
