A 14-year-old hamburger from McDonald's was reportedly preserved by a Utah resident and is still pretty much unchanged.
David Whipple reportedly bought the burger last July 7, 1999 as indicated on the receipt that is still with him. The burger was intended for an enzymes experiment by Whipple and his friends.
Whipple showed the 14-year -old burger to the TV show, "The Doctors." It is still mold-free and only the pickle was affected by time.
