In This Coca Cola Ad From The Early '50s, Suburban White Children Are Subliminally Encouraged To Rap Through The Magic Of Advertising

The young blonde featured prominently in this ad went on to star in a 1983 episode of "That's Incredible."  

As "America's Rappin' Granny," she accurately performed the entire rap from Blondie's "Rapture," and successfully rapped seven stanzas from the Sugarhill Gang's 1979 classic, "Rapper's Delight."
