Just when you thought nothing could no longer surprise you, something ridiculous happens and you're shocked all over again. Last month, a fast food fan dropped thousands of dollars, $14,700 to be exact, on a McDonald's menu items that dates back to the late 90s! Insane, right?

Back in 1998, McDonald's released a limited-edition McNugget sauce to celebrate the release of the Disney movie, Mulan. The special SzeChuan dipping sauce was almost erased from people's memories until someone spotted it in a car.

A lucky Ebay seller found two packets of the Asian-inspired dipping sauces in an old car, they immediately had it up for sale on the auction website.

"I just bought a really old car, while cleaning it I found a packet of this sauce.," the listing states. "After watching the recent episode of Rick and Morty I went online to see if it was worth anything. Turns out it was. Also this comes with a packet of wasabi as well."

Bids started to trickle in within hours and by the end of the auction, the sauces garnered about 187 bids.

This sauce in particular gained popularity after an American animated show, Rick and Morty referenced it in a recent episode.

Ever since this mention fast food lovers were determined to have the 19-year-old sauces back on the McDonald's menu.

An online petition was set up and it has gotten over 20,000 signatures so far. Prior to that, another McNuggets sauce was listed on Ebay with bids as high as $102,000.
