During Thursday's "Halloween Surprise" episode, Ron (Nick Offerman) brings along a special guardian in Andy (Chris Pratt), who appears to be taking his police training seriously, as they go door-to-door in Pawnee.

Check out the video, exclusive to The Hollywood Reporter, to see how Ron handles a sticky situation between the girls. (Spoiler alert: It doesn't exactly go over well with them.)
