It was the end of the world this week on 'Parks & Recreation' (Thu., 8:30PM ET on NBC). We found it rather charming that the Parks Department of Pawnee is so gracious and cordial to this group of fanatics who calculate the end of the world regularly, rescheduling each time the world doesn't end as predicted.

Ron Swanson has even found a way to profit from their zealous conviction. He brought with him some flutes and recorders he'd fashioned at home in his wood shop, and charged exorbitant prices to the believers.

His look to the camera when one of them slyly asked if he'd take a check he could deposit tomorrow -- after the world ended, of course -- was absolutely priceless.
