I used to write down every pizza I ate—how crispy its crust was, the cheese-to-sauce ratio, everything. Then one day, I noticed that I was gaining weight. I was afraid I had been eating too much pizza, but when I looked at my little black pizza book, I saw that I hadn’t ordered pizza in several months! As it turns out, I was just pregnant. I immediately got a large peppers and onions with extra cheese to celebrate.
