It's plate-carriers vs. plungers when Alice (Linda Lavin), Vera (Beth Howland) and Jolene (Celia Weston) participate in a TV quiz show. The category is "musical trivia", and the girls' competition consists of a trio of plumbers, led by peppery oldster Louie (Cliff Norton). For a while, it looks like the waitresses are going to win--but that's when the competition starts flushing up the dirty tricks. This episode was codirected by series regular Vic Tayback (Mel). ~ Hal Erickson, Rovi
