 The "clap" noise was sometimes substituted for actors in the commercials knocking twice against a truck carrying Winston cigarettes, or an actor flicking his lighter twice to the same conceit.Winston cigarettes were sponsors of such television series as "The Beverly Hillbillies" and "The Flintstones".The former series would show stars Buddy Ebsen, Irene Ryan, and Nancy Kulp extolling the virtues of Winstons while smoking them and reciting the jingle.
