Limerick

I didn't think Tom's limerick was very funny.

The limerick is an Irish poetry form.

The limerick, it would appear, Is a verse form we owe Edward Lear; Two long and two short Lines rhymed, as was taught, And a fifth just to bring up the rear.

Take a look. That’s Buffy, Muffy, and Fluffy. Do they have anything in common other than names you could write a limerick around?
