i must, however, question how there can exist such a thing as "leftover pizza". Leftover means you didn't eat it. Are you saying you had pizza, and did not eat it? what kind of a monster are you ?!
Most people don't eat an entire pizza in one sitting.
Most.
If I'm hungry enough I can probably clear half a medium, maybe even a bit more.
