Steve Carell’s long-gestating and super-sized adieu to The Office was watched by at least 8.1 million total viewers and drew a 4.1 demo rating, representing a 20 percent week-to-week gain and the NBC comedy’s best numbers since January 20. Those tallies could inch higher once the 10 minutes of Parks and Rec overlap is abacus’d out of the equation.
