Normally, moldy food isn't the best way to sell a value meal but Burger King is looking at the positive side of the disgusting fungi. A few years ago, a viral video of another fast-food burger refusing to decompose raised questions about the junk we're getting at the drive-thru. To separate his flame-grilled beef patties from the pack, The King is announcing to the world that his Whoppers are free from any artificial preservatives with this beautifully gross time-lapse of a decaying burger. Just make sure you consume it within 34 days. The new Whopper will be available in 400 Burger King locations throughout the U.S. by the end of the year.
