Yes, me too. Reading the caveat "– and she would give each pie away" made a lot more sense.

It's a social commitment at least as much as a creative/culinary one, and since there aren't a lot of people you'd want to give a pie minus a slice to, that keeps the extra calories under control.

Do I exercise and eat healthy?

"Yes, I am in shape (round is a shape)"

A friend of mine tries to bake a spherical pie for pi day (March 14) each year, with varying approaches (and levels of success).

half way there, now you just have to find the frictionless vacuum

Eating enough pie could help with that

The pie calculation for spherical you would be 3*volume / 4*radius^3.
