Do you remember a few years back when Burger King sold a burger with a black bun for Halloween . . . but the coloring turned people's poop GREEN? It turns out they did NOT learn their lesson.
Burger King just started selling a "Frozen Fanta Scary Black Cherry" slushee for Halloween. And based on early reports . . . yup, it's messing with people's poop again.
According to social media, so far the coloring they put in the slushee has turned people's poop black, blue, and green. So drink at your own risk.
