The guys at Cheers inaugurate a marathon poker game, ostensibly for the purpose of teaching Woody (Woody Harrelson) how to play. While the boys are otherwise occupied, Rebecca (Kirstie Alley) bravely holds down the fort -- or rather, the bar -- with the help of Carla (Rhea Perlman). Fortunately, Cheers enjoys one of its busiest nights ever; unfortunately, the bar's liquor license has just expired, forcing Rebecca and Carla to concoct some bizarre, alcohol-free improvisations. ~ Hal Erickson, Rovi
