"I was showing some people how enzymes work and I thought a hamburger would be a good idea. And I used it for a month and then forgot about it," David Whipple told the show's hosts. "It ended up in a paper sack in the original sack with the receipt in my coat tossed in the back of my truck and it sat there for, I don't know, two or three months."
The coat was then moved to Whipple's closet, where it remained until his wife dug it up along with the burger "a year or two" later.
"We pulled it out and said 'oh my gosh, I can't believe it looks the same way,'" Whipple said.
And it continues to maintain its ostensible freshness to this day, some 14 years after it was initially purchased.
Though he nearly sold it on eBay once — and for $2,000 no less — Whipple decided it was better to hold on to the burger for posterity's sake.
"It's great for the grandkids to see," he said. "To see what happens with fast food."
