It is said, that if you understand why Pizza is made round and delivered in a square box but cut into triangles to serve that you can understand a woman.
p.s. I don't do either

The big mystery to me is why there is a special knife for cutting pizzas (and
only pizzas), i.e. the wheel on a handle which rolls as you push it. It's as if it was designed by someone who hadn't grasped the fundamental principle of how knives work.
I won't comment on women.
