A strong cast in a quartet of original playlets by top writers. 1) Lauren Bacall and Robert Preston star in Peter Stone's "A Commercial Break," about truth in advertising and lies in marriage. 2) Neil Simon's "Big Joe & Kansas" (Alan King and James Earl Jones) are a pair of hobos with views on the economic crunch. 3) In Jules Feiffer's "Kidnapped," Art Carney is a bewildered father wearing an earphone-tuned in to his stereo and tuned out to the squabbling sounds of his wife (Elizabeth Wilson) and kids. 4) Herb Gardner's "I'm with Ya, Duke" is about an elderly hospital patient (King), who is given to insulting his young doctor (John Cunningham) and reminiscing about the Brooklyn Dodgers.
