The third episode of Poker Face, “The Stall,” may feel awfully familiar. The title refers to the process of barbecuing meat at low temperatures for long periods of time, during which “a kind of alchemy takes place,” according to George Boyle (Larry Brown). George owns and operates Boyles’ Barbecue, a popular family-run joint in Texas, with his brother, Taffy (Lil Rel Howery).
