This is the meeting that could send the internet into the Upside Down.
The fan theory that Steve (Joe Keery) from Netflix's '80s-inspired hit series, Stranger Things, is the father of Parks & Recreation's Jean-Ralphio (Ben Schwartz) reached its logical conclusion on Tuesday when the actors who play the two characters met up and celebrated their uncanny likeness to one another.
"Dad and son meet because the Internet," Schwartz captioned an Instagram video, where Keery pops out from behind him in a matching outfit before they both mutter, "That's strange."
Now, while on first take, the theory that Steve is Jean-Ralphio's dad may seem completely ridiculous, it is actually eerily possible! Steve was coming of age in the '80s, years before Parks & Rec takes place, AND both shows are located in fictional Indiana towns.
Also, in August, Schwartz did his best to elaborate on the theory for a segment on The Late Late Show With James Corden.
Meanwhile, Keery dropped by ET last month, to discuss the breakout Netflix series, his fantastic, ever-taller hairstyle, and how the Duffer Brothers set the tone for their actors when casting the show.
