Rhyme Of The 'nash'ural Poem by Ima Ryma

Ogden Nash spent effort and time
Writing humorous poetry.
He be extraordinaire on rhyme,
Oft quite unconventionally.
The New York Times called him the best
Producing verses, clever, light,
Which Ogden undertook with zest,
Normally ending with a bite,
Often misspelled or made up words
To make a funny point about
Lots in life, lines massacreds,
Just added to the charm, no doubt.

Famous two liner called 'The Cow, '
Rhymed 'bovine ilk' with 'milk' was how.
