I mean the correct order is the tip with a bite of the crust from one side, then continue to go along that side biting a piece of the crust along with the base pizza. Unless you have something like curry on the side, then you can just not eat the crust at all and use it as breadsticks for the curry.
I'm confused by this comic, because she's literally eating it crust first, which is not the side. And crust first is a 100% qualified way to eat pizza.
Oooh garlic butter is gonna be my next one to try. Pizza and spiiicy spicy curry is my hangover special - leftover curry and make or order pizza and then eat the crusts with the sauce. Garlic butter sounds like heaven though.
E: Tomato soup is also another great one for dipping crusts.
