Here are some of the common myths, reports huffingtonpost.com:
1. Myth: Italians are solely responsible for creating pizza.
Truth: The tomato saucy, cheesy pizza pies as we know them today do have their roots in Naples, but the ancient Greeks are credited with making pizza-like dishes before that.
2. Myth: You can always count on pizza to be relatively cheap.
Truth: There's actually one pizza that costs $1,000 in New York City and it includes caviar and lobster.
3. Myth: Most pizzas are ordered with plain cheese.
Truth: According to a data compiled by food delivery service Foodler in 2013, more people order pizza with toppings than just cheese.
4. Myth: Pepperoni is one of Italy's greatest contributions to pizza.
Truth: Pepperoni is an Italian-American creation. In Italian, the word "peperoni" actually means "large peppers" (as in bell peppers).
5. Myth: Pizza should only be reheated in the microwave or oven.
Truth: They are great options, but so is the grill.
