Kate Flannery, beloved for her unforgettable portrayal of Meredith Palmer on "The Office," joins the show to discuss her latest role as Principal Saperstein in Hulu's new comedy series "All Night." The unique premise features an entire season taking place during one graduation night at a high school, where students are locked in for their grad night dance without their phones, forced to navigate their final hours together before moving on to the next phase of life. Flannery describes her character as "the human buzzkill," tasked with the impossible job of controlling hormonal teenagers who don't want to listen, while working alongside talented young actors including former Disney Channel stars and Ali Grant from "Suburgatory." She reveals that maintaining continuity throughout the single-night timeline meant the cast couldn't gain an ounce of weight during filming, and fans have already begun binge-watching the series since its recent Hulu release.

Beyond her new series, Flannery answers a fan-submitted question about where Meredith Palmer would be five years after "The Office" documentary, playfully suggesting she'd be "four and a half years sober" before joking that Meredith would likely still be drinking, partying, and working at Dunder Mifflin as long as they'd have her—possibly even in a relationship with the guy she was dancing with at Phyllis and Bob Vance's wedding. She also confirms the behind-the-scenes secret that yes, she really did lick hand sanitizer on the show, though it was specially made with clear gelatin and club soda rather than actual sanitizer. Flannery discusses her other recent roles, including the beloved crossing guard Sandy on "American Housewife" (with hints she may return) and Mean Marge on "Brooklyn Nine-Nine," humorously imagining that if all three characters met, "a fist fight would break out" and "television as we know it would never be the same." She also promotes her ongoing Christmas tour with Jane Lynch and their album "A Swingin' Little Christmas," featuring ten classic carols and five original songs, with upcoming performances at the Carlisle Hotel in New York City and Pittsburgh in early December.
