From the Variety article linked above:
Do you have a favorite mishap, especially when you were so close to getting a take?
I think Kathryn Hahn…she would break the scene a lot of times because she would say something so ridiculously funny, and Seth would crack up, or half the cast or the operator would start laughing. Kathryn is so funny and has such good timing and improv that she can’t help but inject these brilliant moments. There were a lot of takes where she would say something just totally unplanned and hilarious, the take would be ruined, but we would then take that line and reincorporate it into the scene in the next take, and we would keep going. She was an amazing source of comedic relief at all times, and a wild card that was very much needed and adored in the show.
I pictured that in Episode 3 happening often.
Hahn is awesome. And her being quick-witted and funny puts her over the top. She's a hall pass if ever there were one.
