Pop culture phenomenon yesterday, Halloween costume today.

In case you missed it, the Internet got excited last week about Burger King's new Halloween Whopper, because it has a black hamburger bun. Not because of how it tastes, word is it's not even that good. But because of the aftermath. The black bun is apparently making some people's poop turn green.

Now, you can celebrate that side effect with a couples Halloween costume.

HalloweenCostumes.com has a guide for what to buy from them if you want to dress up as a black Whopper and a piece of green poop. It's not too tough. They already sell a full-body poop costume, you just have to spray paint it green and pair it with a green wig. They also sell a hamburger costume, you just have to use a Sharpie to color it black.
