After sitting in a “really old car” for 20 years, a packet of McDonald’s Szechuan Sauce is selling for nearly $15,000. In “Rick and Morty’s” third season premiere on April 1st, Rick mentioned the it, saying that he’s driven by the McNugget teriyaki dipping sauce, even if it takes “nine more seasons… or 97 more years” to find it. Ten years ago, the sauce was served alongside wasabi sauce with McDonald’s chicken nuggets to promote Disney’s animated feature “Mulan”. The sauce hasn’t appeared again until the listing was posted on eBay saying, “I just bought a really old car, while cleaning it I found a packet of this sauce. 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.”
