They always have to end with a pun --
Preferably one that's sexual.
My gags intellectual
Have nowhere to go when it's done.
The limerick form, though quite charmin'
And frequently slick and disarmin',
In rap finds no takers
With movers and shakers --
Except maybe MC Paul Barman.
Although for fixed forms I'm a dork,
My limericks just don't seem to work --
Or else, like that line,
They just don't really rhyme.
I'll invent a new form, called the 'Cork'.
