What is the most popular ice cream flavor in the world?

Well, there are so many flavors out there, it's hard to decide. My top three favorites are Chocolate Chip, Mint Chocolate Chip, and Chocolate Chip Cookie Dough. (But remember, raw cookie dough contains raw eggs, which can pose a number of health risks, but are usually harmless, espescially in processed dough made for ice cream and not for baking. Just a pro tip.)
