There once was a ribald Sestina
Accompanied on concertina.
It's metrical pace
Was a blooming disgrace
But the Poet - well - you should've seen 'er.
A Haiku arriving for dinner
Complained it was getting much thinner.
The amount that it ate
Hardly covered the plate
Of this seventeen syllable slimmer.
There once was a French Villanelle
Whose essence was not very well.
Yet it had the potential
To be existential,
Though Albert Camus couldn't tell.
