Tides

This just came to me.

I threw a lasso 'round the Moon

I thought it would be hard

But it was not

I swear

But there

I was. No plot

I tied it to my yard

But I released it really soon

It caused a terrible typhoon

Earth had its surface scarred

Seas rose and brought

Despair

The dare

Misled my thought

My mind was surely marred

For I was acting like a loon

Somewhy it struck me as a boon

To have it under guard

On the right spot

To stare
