More than 20,000 supporters have signed a petition calling for McDonald's to bring back a special sauce for its Chicken McNuggets, and it's thanks to a cult-favorite cartoon. Rick and Morty, a popular animated series co-created by Dan Harmon for the Cartoon Network's Adult Swim roster, hasn't put up a new episode since October 2015, when it aired its second-season finale, the Atlantic notes. So fans were giddy with excitement Saturday when the network unexpectedly aired the first show of Season Three—and the episode's final moments had an additional surprise. Per Business Insider, Rick, who plays the mad-scientist title character, revealed his innermost motivations, and they involved a plum sauce the fast-food chain hasn't offered in nearly 20 years.
"I want that 'Mulan' McNugget Sauce. ... That's my series arc, Morty," he tells his grandson. "If it takes nine seasons, I want that McNugget Szechuan sauce." What the deranged patriarch referred to is a condiment McDonald's offered as part of a co-branding effort with Disney in 1998 to push its movie Mulan. The special sauce is now making an appearance on eBay—though the listings mostly appear to be Rick and Morty-inspired jokes—and the show's writers even put out a plea on Twitter, asking McDonald's: "You wanna get in on this? Call me." The restaurant account's reply: "McNugga Lubba Dub Dub" (a twist on one of Rick's catchphrase); a top Mickey D's chef also said, "I'll see what I can do." Business Insider notes a live-action version of Mulan is due out in late 2018, so ... the McNugget's in your court now, McDonald's. (The chain is trying its hand at "cleaner" nuggets.)
