THE NATIONAL HEALTH COW

I strolled into a farmyard
When no-one was about
Treading past the troubles
I raised my head to shout.

'Come out the Cow with glasses,'
I called and rolled my eye.
It ambled up toward me,
I milked it with a sigh.

'You're just in time' the cow said,
Its eyes were all aglaze,
'I'm feeling like an elephant,
I aren't been milked for days.'

'Why is this? ' I asked it,
Tugging at its throttles.
'I don't know why, perhaps it's 'cause
MY milk comes out in bottles.'

'That's handy for the government,'
I thought, and in a tick
The cow fell dead all sudden
(I'd smashed it with a brick).
