To wit, Barbara Mandell sings in her early '80's hit "When Country Wasn't Cool:"
That said, Barbara Mandrell is a Texan, so while she used the word "Coke," she could have very well been singing about putting peanuts in her Dr Pepper. No matter, placing peanuts in your Dr Pepper (or Coke) is done for two reasons. One, the peanuts make your Dr Pepper fizz. And two, it tastes good. The salt from the peanuts cuts the sweetness of the soda, plus it's entertaining to have a bit of crunch in your mouth as you sip."I remember circlin' the drive-in/
pullin' up and turnin' down George Jones/
I remember when no one was lookin'/
I was puttin' peanuts in my Coke/
I took a lot of kiddin', 'cause I never did fit in/
now look at everybody tryin' to be what I was then/
I was country, when country wasn't cool"
