20-year-old burger???

Since the news broke about a McDonald’s hamburger bought 20 years´┐╝ ago and looking exactly the same as it did when it was purchased, I have decided I will only eat those burgers. I will live forever!´┐╝ McDonald’s vehemently denies that the burger could ever look like a fresh one. What else could they say? … More 20-year-old burger???
