The Cow comes home swinging

Her udder and singing:

 

‘The dirt O the dirt

It does me no hurt.

 

‘And a good splash of muck

Is a blessing of luck.

 

‘O I splosh through the mud

But the breath of my cud

 

‘Is sweeter than silk.

O I splush through manure

 

‘But my heart stays pure

As a pitcher of milk.’

 

from the collection ‘The Cat and the Cuckoo’
