There once was a girl with a pen
Who wrote a few lines now and then
But at night in her bed
She would cower in dread
From that terrible limerick yen.

Refers to the fact that most of my limerick inspiration comes when I can’t sleep, and instead of counting sheep (bah, bah, bah), I count lines of anapestic meter (bah-BAH-bah-bah-BAH-bah-bah-BAH). See Confessions of Limerick Junkie for more on this.
