As I walk to my door, looking cool (ish)
My thoughts tend to turn to the ghoulish.
I quicken my pace
Though there's never a trace
Of real danger. I look rather foolish.
I don't know whether you noticed, or whether it worked, but what I tried to do here was quicken the rhythm of the limerick through the third and fourth lines, before the abrupt halt in the fifth. To match the quickening pace in the graph, you see.
