Dr. Pepper is made by wizards.

Have you ever drank a Dr. Pepper? The taste is pretty unique. Have you ever drank a Dr. Pepper mixed with anything? It tastes like water. Not even sugar water, just flavorless liquid. You can try this yourself. Pour yourself a half-glass of Dr. Pepper, and add a small amount of cola to it. You will be amazed. I have a hunch that good ol' DP isn't actually flavored. Instead, it's enchanted by some organization of secret sorcerers to give it an intangible and unexplainable flavor that doesn't really exist. It's all in your head.
