When I was 8 years old, my sister ordered an XL pizza from papa johns. And I said "Ok......but what are YOU having?" She laughed it off as me saying I'd eat the whole thing myself. I saw no joke. So I made her order a second pizza for herself. She got a small. And when I was done with my pizza, I ate half of her pizza. She then accused me of playing some prank on her. She searched her apartment up and down claiming I was hiding the pizza somewhere. I was like "YOU WATCHED ME EAT MOST OF IT!!!"

My stomach did not have an "off" button. At least not until decades later when they removed 2/3rds of my colon. Now I can eat something small to medium sized and feel like I'm full.

But back then? I honestly think if you'd have put 10 XL pizzas in front of me, I'd have eaten them all if I liked the toppings. Then asked for snacks later.
