Donkey mates with horse

The two begat a mule

In the subsequent course

They spit out a fool

He travelled the world

Braying like a rabid goose

His exposed plans unfurled

On feckless foals he was loosed

He couldn't see beyond

His unfruitful nativity

He could never spawn

Beyond stubborn naivety

Yet he keeps humping

In hopeless faith

That he can still

Reproduce a perfect

Image of himself

Clueless Equus Asinuus!

Prepared for procreation

Mechanical instigation

In the absurd cicumstance

He won't be the one

Put out to grass

When he shoots blanks...

Heaven help you!

Hapless equinine ass!
