Inspired by his therapist's helpfulness, Chris starts a prototype 3-1-1 service and asks the parks department to answer calls.
However, they are unable to get out of the parking garage due to the presidential motorcade being nearby and security not letting any cars near the area.
They push it back into the parking spot and end up laughing about the experience, with Ben offering to pay for plane tickets to Pawnee the next weekend.
These twelve real historical figures are mostly politicians, of both conservative and liberal parties, and several had been specifically mentioned on previous episodes.
They include Hillary Clinton, Sally Ride, Madeleine Albright, and Olympia Snowe (who had appeared in the episode "Ms. Knope Goes to Washington").
