Obviously, you would never eat a burger that has been sitting around for 30 days, but don't you wonder what it would look like?
The makers of Buzzfeed Video performed their very own unscientific decay test: What do six popular fast food burgers look like after being left in a jar for a almost a month?
While most of them were covered in blue and grey mould, others still had their buns, burger patties and even some cheese intact. Gross.
A very similar experiment of this kind was done when documentary filmmaker Morgan Spurlock did his very own "The Smoking Fry" test in his 2004 movie, "Super Size Me." However, in Spurlock's video, he took several McDonald's items like fries and burgers and compared them to fries and a burger from a local restaurant. The result? Let's just say you'll think twice before ordering fries at McDonald's.
Watch the video above to find out why that last burger freaks us out so much.
