here's two (almost)...
There once was a man who insisted
that his annkle was sprained and not twisted
he hobbled about
and gave a great shout
when he stepped on a step, but he missed it!
A terrible poet was Jenny
Her limericks weren't worth a penny
In technique they were sound
Though often she found
whenever she tried to write any
she always wrote one line too many
(Sorry, so sorry...)
