Acia Berry
A mildly ok fruit native to Brazil that has only middling levels of antioxidants—less than that of Concord grape, blueberry, and black cherry juices, but more than cranberry, orange, and apple juices. Many internet scams have been promoting it as one of the most amazing super-fruits on earth. This is a lie.

Guy 2: You're being an idiot.
