The other day, my son was eating a piece of pizza.
Instead of simply eating it, he commenced a full examination. He examined every crack and crevice. "Mama," he said after he was finished. "Did you know that every slice of pizza is unique - like a fingerprint?"
"Well, Bubba," I said. "I hadn't really thought of it. But I suppose you're right."
"Yes, I am." He flipped the piece over. "Look at the oven burn here. It's unique. No other piece has marks like that." Then he grinned. "I know what they are."
"What are they, Bubba?"
Okay. So, ladies and gentlemen, next time you eat a piece of pizza, flip the thing over (careful not to lose the toppings) and check out the pizza prints!
