Teens today are probably too sophisticated for this sort of nonsense, but back in the day, I promise you I would have had one of these in the tool pocket of my painter's pants: Lip Smacker Coke Cup Lip Balms ("delivers the authentic taste of Coca-Cola while providing extended hydration to your lips.") In Coca-Cola, Cherry Coca-Cola, Sprite and Fanta Strawberry. About $4 each at Lip Smacker.
And yes, they still make Dr. Pepper, plus scads more flavors, including Kettle Corn, Pumpkin Latte and Double Cheeseburger. (Found via Pop Sugar)
