Big Bad John

A song by Jimmy dean. Big John was the epitome of hard work and masculinity. Standing at 6'6" and weighing 245 lb, broad at the shoulder and narrow at the hip. He sacrificed himself to save others when the mine he was working in collapsed

Every mornin at the mine, you'd see him arrive. He stood 6 foot 6 and weighed 245. Kinda broad at his shoulder and narrow at the hip, and everyone knew you didn't give no lip to big John.
Big John, big John, big bad John.
