[Chris Pratt]’s kind of a writer’s dream. I’ve said this before, but it’s worth repeating: He has the best improvisation in a cast full of world-class improvisers. Amy Poehler and Aziz Ansari and Nick Offerman and Aubrey Plaza. Like, people who trained and are great in improvisation. The best improv in the show’s history was Pratt’s, and it was in “Flu Season,” when Ben is walking Leslie out the door to go to the doctor, and Andy is just taking over as Ron’s assistant. As they’re walking by, Pratt says, “Hey Leslie, I typed your symptoms into the thing up here, and it says you could have network connectivity problems.” [Laughs.] If I could write a joke that good, I would be a happy man. And it was completely improvised. He’s just so in the moment, and all of those actor-y terms. He’s so present and in the moment and fully fluent in his character that he can make up perfectly formulated jokes like that on the spot, and it’s incredible. He’s improved every episode he’s ever been in.
