My mom sang the first verse about the two sons. She sang Bohunkus. A Bohunk is someone from the Czech Republic. In Western Pennsylvania, a hunky is someone of Eastern European ancestry, Czech, Slovak, Serb, Croat, Russian, Ukrainian etc. are all hunkies. It's considered a perjorative, but I know people, among them my next door neighbor, who proudly call themselves Hunkies. He's got Hunky4 for his license plate.
