Pizza is a food that people will get in fights over. Just put two people in a room, one who thinks that pineapple is a good topping, and one that doesn't think that fruit belongs on a pizza at all. They'll end up tearing each other apart... over food! It's not just what toppings are on the pizza. There are arguments over dough thickness and what sauce you use too. One major argument though, comes from how you eat pizza. Do you fold it up New York style, or do you use a fork and knife like a psycho?
Pizza was made to be eaten with your hands, like a taco. When you eat it with a fork and knife you're not connecting with the food. Plus it's much easier to avoid the crust when you're eating it with your hands. Take a few bites then fling that crust in the air.
