A '90s-era McDonald's Szechuan dipping sauce has hit over $99,000 on eBay after the season 3 premiere of Rick and Morty went viral this weekend.

Without revealing any spoilers about this particular episode of the Adult Swim cartoon, the show's mad scientist grandfather, Rick, is desperate to find some of the limited-edition dipping sauce McDonald's released in 1998 as a product tie-in to Disney's Mulan.

It turns out the show's fans are equally desperate for the sauce.

Some have even started showing up at McDonald's and asking for the sauce.

Another started a change.org petition that currently has over 17,000 signatures.

But what's even crazier about this newfound love for vintage McDonald's sauce, is that someone is selling a photograph of the Szechuan dipping sauce on eBay (not even a real packet of the sauce!) and people are actually bidding on it. At press time, the current bid is at $99,100 (yes, really).

Here's the description:

You are bidding on an authentic autographed photograph of that Mmmulan McMcMcNugget sauce, printed shoddily on plain paper and sent in an ordinary USPS stamped envelope. You will also receive a complimentary sense of generalized bamboozlement for having the poor judgment to spend good money on this particular auction. That's my series arc! #NineMoreSeasons

Hey, at least 100 percent of the winning bid will be donated to Habitat for Humanity, according to the listing.

The auction ends Sunday, April 9 so there's plenty of time for this whole thing to get even crazier.
