The following is a limerick which explains what a limerick is:
The lim’rick packs laughs anatomical
In space that is quite economical,
But the good ones I've seen
So seldom are clean,
And the clean ones so seldom are comical.
I have decided to follow the same trend to test my limerick writing skills:
There once existed a self-centered prick
Whose attitude would make a leper sick
For it was without cynicism
He died of an overdose of narcissism
Then the coroner discovered he had a limp shtick
There once was a British boy named John Frank
While fetching water from a parish tank
A nun came his way
And to her he ‘say
‘tis fun to look at nude photos and ‘fill in the blank’
