During the '90s, I remember seeing a commercial for a magazine; I'm fairly certain it was for TV Guide. There was a tap dancer in the commercial underscoring the magazine's features and subscription price. I remember thinking, "Is the dancing essential for getting the information across? No. Still, maybe the producer of the commercial had a friend who needed the work."
Although magazine commercials and tap dancing don't usually go together, it's an unusual but decent way to promote the product. Besides, maybe the intent was to convey to readers that the magazine has class. If so, that's not a bad strategy.
The Gentrys might have had the right idea, then, advising us to "keep on dancing."
