Classic comic 688 - Self-Description

The twenty eight words in my rhyme
Have vowels forty seven - a prime.
Its five lines (a surety)
And syllables thirty
Plus six, letters hold one one nine.

Original comic here.

Comic 854 - Learning to Cook

We'd all love to cook from ingredients
But we're baffled by their disobedience.
The best form of eats are
Still takeouts and pizza
Which win on both taste and expedience.

Original comic here.

Classic comic 757 - Toot

There once was a young man from Jackson
Who always would carry a klaxon.
When braggarts would warn
"Not to toot my own horn...",
BRAAAAAAAAAAAAAAAAAAAP! tooted that fellow from Jackson.

Original comic here.

Another one that might appeal to fans of the recent "Consecutive Vowels" comic.

Comic 853 - Consecutive Vowels

The delight of a man from Kauai
Were strings of a, e, u and i.
When vowels started queueing
The passion ensuing
Resounded all over Hawaii.

Original comic here.

Comic 852 - Local g

There was a pole vaulter from Mold
Who wowed London's crowd and won gold
But in spite of his brio
He'll struggle in Rio
Cause down there, g's value won't hold.

Original comic here.

An extrapolation from the comic's general theme, rather than a versification of the comic's events.

Classic comic 301 - Limerick

I used to love going on Slashdot
But now I'm shocked how bad that trash got -
My sarcasm tenuous
The mods disingenuous
Keep rating plus five (that's the cashpot).

Original comic here.

Comic 851 - Na

Na x 8 hey hey goodbye!
Na x 10 Katamari!
Na x 8 Batman!
But Wil Pickett's scat (man)
Takes na into infinity.

Original comic here.

Lots of the dreaded eye-rhyme here (for best results, I recommend pronouncing them all to rhyme with 'goodbye'). Too many nas tend to make things very difficult for the versifier who has limited syllables at his disposal.
