I am illiterate.
I know what the thread is about, but "Good Times" is referenced. In addition, the audio touches upon "Good Times." Nevertheless "Good Times" was a Minstrel Show and this woman's call to fame is as an unashamed Minstrel.
I could understand someone claiming that "JJ" or even maybe Wilona being a minstrel but, what exactly did Thelma do to earn that handle???
