Check out this ad for Jamba Juice's Cheeseburger Chill Smoothie. It's totally awesome. And, for those of you whose brains have been dimmed by a steady diet of greasy fast food, totally fake. "It does seem some burger chains are getting into the smoothie business," reads the company's website. "Which to us is about as weird as a Cheeseburger Chill Smoothie. So we're sticking to what we know." Those who get in on the joke can download a coupon as well.
