Pizza-within-a-pizza was previously a menu item that existed only in hypotheticals.
"Inception was okay," people said as they exited theaters two years ago, "but what I'd really like to see is a pizza-within-a-pizza. Yumyumyum."
"What's my favorite topping?" they asked themselves as they filled out their online dating profiles. "Pizza! Pizza on top of pizza!"
"Don't you see, you fools?" exasperated grad students yelled at their colleagues, banging their fists into chalkboards. "Pizza-within-a-pizza can never occur! The pizza would become too unstable!"http://www.esquire.com/blogs/food-for-men/pizza-hut-double-sensation-14882219?src=nl&mag=esq&list=nl...
