A parrot was sick, yes quite chronic;
he took Henry's poems for a tonic.
He let out a squawk, now all people talk.
Supersonic he died on moronic.

Another parrot, to cultivate mating,
read those poems, (although they were grating!)
Parrot fell with a lurch right off of his perch:
his lady issued 'ones' for her rating!

Shelley Byron Keats
