Sheriff Roy Tillman’s sinister line to Danish Graves in Fargo season 5, episode 8, “Blanket,” is a strange callback to a 25-year-old episode of a classic sitcom. For the first time in the season, “Blanket” sees Tillman one step behind his enemies. In retaliation for Tillman blocking Lorraine’s bank purchase, Graves recruits three debtors to legally change their names to Roy Tillman and mock the real Tillman at a debate on the campaign trail. This prank leads to Tillman losing his temper in public and jeopardizing his re-election campaign.
