Steve Jean RalphioThe resemblance between the characters of Steve from "Stranger Things" and Jean-Ralphio from "Parks and Recreation" was so uncanny that the Internet decided Steve was somehow Jean-Ralphio's real father (forget Henry Winkler).

Fans concocted a pretty reasonable explanation for it all, and their theories were basically confirmed by the actors themselves, Joe Keery and Ben Schwartz. They got in on the fun by posting some eery photos of the two looking basically like identical twins. And they upped the ante by appearing on "The Late Late Show With James Corden" last night.

In the video, Schwartz and Keery sit down with a reporter and discover some odd coincidences about themselves: they both make their own clothes; they say the same thing at the same time; they use the same gestures; and they even have a secret handshake ... they didn't know they had!

It's even stranger than the Upside Down!
