McDonald’s is having fun with the viral call to bring back an obscure, limited edition nugget dipping sauce from the ‘90s, all thanks to Adult Swim show Rick and Morty. According to Time, a 64-ounce jug of the chain’s discontinued Szechuan Sauce was sent to series co-creator Justin Roiland, who has featured a character’s cravings for it prominently in the show’s third season. Roiland tweeted a photo of his bounty along with a letter sent by the chain, which claimed it had to open a time portal to get him the goods. Per iO9, the letter signed by a “Chef Mike” said, “We wish we could have brought more sauce through, but we couldn’t risk keeping a portal like that open.”
The note went on to joke about the dated trends that could slip back via the portal if they weren’t careful, including “puka shells, bucket hats and boy bands as far as the eye could see.” Roiland and his team have created buzz on social media about the plum sauce, which was released in 1998 to promote Disney’s Mulan. His pleas to bring it back caught on around the web, sparking a Change.org petition that now has over 41,000 signatures. McDonald’s has hinted that Roiland won’t be the only 1998 culinary time traveler—Chef Mike’s note ended by saying “a few lucky fans” will get to “experience the glory,” and the chain teased a photo on Twitter Sunday featuring three more jugs of the sauce alongside the time and date of the Rick and Morty show's return to Adult Swim.
