Inconsequential indigestion

This limerick never did display much sanity
It has no brain, and it is less than jaunty
Although it has fish and oil
It has no liver at all —
Allusion ate it with a nice Chianti.   ⁰/₁₀

There once was a limerick which didn't rhyme or scan
And was unnaturally preoccupied with its own internal organs
Its otherness insistent
Was less than consistent (rhymes)
And altogether gave language itself indigestion.   ¹¹/₁₀

A limerick self referential
Appeared to have formal potential
But though form is content
The form of this one went
On tedious and inconsequential. (True)   ⁰/₀

By contrast this last of the four
Has a plot line you cannot ignore
From the Fall to Salvation
And in flashback — Creation —
It still proves a bit of a bore. (Hēllò)   93.2%
