The show's last new episode aired in 2015.
In the new episode, title character Rick mentions going back in time and how much he liked McDonald's "Szechwan Sauce."
But the sauce is now "no longer available," at least not in this reality.
The sauce was part of a promotion in the late '90s for Disney's Mulan.
The reference led to the sauce's name trending on Twitter.
Alright now @McDonalds really needs to bring back their Szechwan sauce or else— Alex Brown (@alexbrownlol) April 2, 2017
The official Rick and Morty account got in on it.
Then the official McDonald's account responded.
And that's the way the news goes!
