Every Pawnee citizen moment (including the ones not shown here) is comedy gold. Yet they are a small percentage the show. Because the show is so damn funny, they don't need to rely on the 'Springfield' like cast of citizens to get laughs.
The "HE CAN FLY!" line had me laughing so hard when it aired, it was properly embarrassing.
As a government employee, I can tell you this is exactly what dealing with the public is like. Nobody ever comes to a public forum to tell you you're doing a good job.
