He may have been little in stature (abot 4'11"), but he was big in country. In his life time, he was the oldest member of the Grand Ole Opry and was inducted into the Country Music Hall of Fame. He was also known for his novelty songs, this one probably being his most well-known. I have no idea what the song's eponymous line is supposed to mean, but I assume it's one of the comedic insults in the chorus which are directed at Dickens for his obliviousness to the plight of others. Clever guy, funny song. R.I.P. Jimmy.
