It’s a big month for people who love novelty foods: In addition to a staggering spectrum of candy, October has also ushered in Burger King’s #HalloweenWhopper—their signature burger, but with a black bun.

So far, so pointless—though that never stopped anyone from ordering something at a drive-thru. And in terms of taste/presentation, it doesn’t seem there were many complaints. Until these customers hit the bathroom.


Inevitably, some folks started snapping photos of their green excrement. Don’t scroll down any farther if that’s not something you want to see.


While it may be alarming, green poop is generally nothing to worry about, health-wise. As a former roommate of mine discovered after eating a giant bag of green apple licorice twists, it’s just what happens when you ingest an ungodly amount of food coloring. In fact, “why is my poop green” ranks among the most commonly Googled queries in the English-speaking world.

Burger King has yet to comment on this apparently unforeseen side effect of the Halloween Whopper. It certainly suits the spooky season, however.
