I’ve noticed that many otherwise diversified poets don’t write limericks, and that many limerick writers tend to specialize, generally avoiding other verse forms. I wonder if this explains the former:
The Neglected Limerick (Limerick)
By Madeleine Begun Kane
The lim’rick is often neglected
By poets who deem it infected
With lewdness beneath them.
It’s time to unsheathe them,
Wielding limericks clearly erected.
