It’s Dolly Parton!
Dolly is known as “The Queen of Country Music”, as well as for being one of the best selling artists of all time.
Between 1974 and 1980, Dolly consistently charted in the country Top 10, with no fewer than eight singles reaching number one. During this time, Parton had her own syndicated-television variety show called ‘Dolly!’, and her enormous country rack became a punchline to a joke involving Kenny Rogers and some islands in a stream.
Even to this day, Dolly Parton remains the most popular punchline to “boob” jokes told all over the world.
