Over the summer, Netflix released a new original sci-fi adventure series in Stranger Things, and the show quickly earned plenty of favor from both critics and viewers. Created by Matt and Ross Duffer, Stranger Things follows the town of Hawkins, Indiana after a young boy named Will Byers (Noah Schnapp) goes missing in the fall of 1984. Although many are skeptical of anything strange going on, Will's friends - with help from a girl named Eleven (Millie Bobby Brown) - discover The Upside Down and a monster that captured Will. Given the positive response to season 1, Netflix renewed Stranger Things for season 2, and the series may have already resumed production.

While Stranger Things' devoted fan following wait for season 2 to drop on Netflix, many have begun theorizing what the season 1 finale could mean for Hawkins, Indiana, as well as what happened to Eleven. However, not all fan theories have to do with season 2. In fact, one particularly popular theory posits that Stranger Things' Steve Harrington (Joe Keery) is the biological father of Parks and Recreation character Jean-Ralphio Saperstein (Ben Schwartz). Now, Keery and Schwartz come together to set the record straight about their characters.

In a sketch for The Late Late Show with James Corden [above], Schwartz and Keery don matching outfits and sit down for an interview with Entertainment Tonight's Nischelle Turner. Although the actors are doubtful at first of their characters' shared connection, they eventually admit that it does seem as though Steve is Jean-Ralphio's father. Earlier this week, Schwartz previewed the sketch with a couple photos and a video of himself with Keery. Take a look:

According to the fan theory, Steve Harrington would be Jean-Ralphio's biological father since Parks and Recreation introduced Henry Winkler as Dr. Saperstein - the (presumably adoptive) father of Jean-Ralphio. However, there are a few differing theories about how this came about, many of which are documented by Uproxx, with one stating that Steve and Nancy had a baby but were incapable of taking care of the young Jean-Ralphio, so Steve's brother Dr. Saperstein adopts the child.

Of course, these theories are simply a fun way to explain the uncanny resemblance between Keery and Schwartz - as well as some of the similarities between Steve and Jean-Ralphio - and it's unlikely the Duffer brothers will comment on their validity. However, with season 2 of Stranger Things planned to debut on Netflix sometime in 2017, fan theories like the one concerning Steve and Jean-Ralphio are an entertaining way for viewers to keep talking about the series - and maybe even win new fans over to the show.
