"The Four Bitchin Babes" did a "spin off" of this song, similar tune, similar theme. This tractor-trailer runs down a hill. It's loaded with viagra. It crashes into a public water supply. Guess what happens to all the men in town? The ballad is called " Viagra in the Water" Need I say more? God bless the spirit and soul of Harry Chapin! It's too bad he passed with a tire and wheel rim in his face. I can think of better ways to pass. In a humorous way, I think it was a tribute to Harry! Thanks, girls! Harry is still laughing his butt off over that.
