TVLine

"We were like, ‘Can this be done?’" said creator Michael Schur of Thursday's episode, which was planned "to the millimeter" way in advance. “The first day of shooting, there was just a little panic about, ‘What if none of this makes sense?'” adds Josh Siegal, who co-wrote the episode with Dylan Morgan. Schur adds that preparation included "a ton of advance warning, and we finished the script really, really early, then we did a bunch of things along the way."
