…our goal was to rewrite the entire OED [Oxford English Dictionary] in limerick form. A tall order? Yes, admittedly it was but when we began we had hoped, with your assistance, to have completed this project before our grandchildren were all dead.
I like this one:
The apostrophe‘s often abused:
It gets battered, and bruised, and misused.
On a plural, a blight;
For possessives, just right,
Barring “its”, which leaves people confused.
(Incidently, Limerick is a town in Ireland.)
