There once was a fellow from Perth,
who was born on the day of his birth.
He was married, they say
on his wife's wedding day
and died when he quitted the earth.
There is a certain thing to limericks, something catchy. But one has to know the form.
A limerick consists of five lines. The first two lines rhyme, and are longer than the third and fourth lines, which rhyme. Then the last line is as long as the first two lines and rhymes with them. But that's not all. The metre matters, too. if the rhythm isn't right, the poem isn't right.
As you can see, I like to stick to form poetry.
