From the are-you-freaking-serious files: 7% of Americans ADULTS surveyed by the Innovation Center for US Dairy think brown cows make chocolate milk, while 48% know that's silly- but have no clue where it comes from. So, apparently the Chocolate Syrup Lobby is not doing it's job. Fun Fact: the topic is even covered on the facts and myths section of the Innovation Center for U.S. Dairy's site: "Chocolate milk — or any flavored milk for that matter — is white cow’s milk with added flavoring and sweeteners."
There you have it America, this is why we can't have nice things.
