Winston was the first sponsor of the Flintstones back in 1960 and produced a few commercials. Here’s another if you haven’t seen it yet.
This one starts out with an overzealous shopkeeper explaining to his bird it’s time to get back to work. Fred walks in to purchase his pack of Winston Cigs and gets stroked for approval by the shopkeeper, whilst he puts one in his mouth.
Fred objects to this sales/marketing pitch, I mean, he is a loyal customer and all. The shopkeeper tells us he’s “practicing,” presumably his sales pitch to lure new smokers. But this practice is fruitless; we learn immediately after his practice pitch that everyone knows “Winston tastes good, like a cigarette should.”
