   • I find that the best train
     Is the morning express train,
     Which leaves Binghamton at 1:20,
     And gives me time enough, plenty,
     To get over the Hudson
     Before you've got your duds done
     On Saturday evening,
     So you needn't be grievening.1905, Marie Hansen Taylor, Lilian Bayard Taylor Kiliani, On Two Continents: Memories of Half a Century, page 83
