Though Netflix’s Wet Hot American Summer: First Day of Camp stands perfectly fine on its own, one of the distinct joys, for fans of the original 2001 film, are all the Easter eggs, callbacks, and origin stories of beloved characters. And while we could spend all day enumerating the many, many inside jokes, there’s one in particular that stands out as especially important in the legacy of Wet Hot American Summer and its co-writer/director David Wain.

In the first film, when trying to get out of an awkward conversation, Janeane Garofalo’s Beth invents a fictional appointment with someone named Jim Stansel. You know, Jim. He’s that guy.

So it’s kind of cute that when Michael Cera’s lawyer shows up in Episode 5 of the prequel series, his name is, you guessed it, Jim Stansel.

But die-hard fans of the greater Wain-verse (Is that a thing? Sure, why not) know that the Jim Stansel joke isn’t just contained to misadventures of Camp Firewood. There’s a character named Jim Stansel in several of Wain’s other films like The Ten, Wanderlust, and Role Models. It’s not the same character; Stansel has been everything from a newscaster to an evil corporate lawyer to Wain regular Ken Marino. But during a Reddit AMA back in 2012, Wain explained the long-running joke:

Jim Stansel was the name of a guy who used to work with my dad when I was like 10 years old. We have a super-8 movie of him up in a hot air balloon for a radio station promotion in Dallas, and my dad’s going “that’s Jim Stansel! That’s Jim Stansel!” and the name has always stuck in my head. I just love the name!

So that’s why, even though (spoiler alert) Michael Cera probably won’t be back for any future Wet Hot American Summer projects, we probably haven’t seen the last of Jim Stansel. You know, Jim. He’s that guy.
