Burger King’s black Halloween Whopper turns your poop green BURGER KING This Burger King Whopper appears to be turning consumers’ poop green. The scariest part of Burger King’s Halloween Whopper doesn’t happen until after you eat it. Something in the burger’s pitch-black bun turns eaters’ poop a ghastly bright green — sometimes for as long as three days. "The Halloween Whopper turns your poop green," tweeted John Kritzman. "And not even sickly green. Like cartoon green. Comical green." http://m.nydailynews.com/life-style...en-whopper-turns-poop-green-article-1.2386174 Anyone eat one and experience this?
