It's a fact in life that there are just always going to be competitors. That's just life! it could be two Irish dancers dueling their best moves on the stage, or Chick-fil-A and Popeyes going to head-to-head in the fried chicken sandwich wars, or people who think the white and gold dress is black and blue. I really just wanted to bring this up again.
Of course, we can't leave out Pepsi versus Coke, Sprite versus 7 Up, and Canada Dry versus Schweppes in their own category that is soda competitors.
