I must try haiku,
There is nothing left to do,
But try something new,

Have I got it now?
Should I not include a cow?
I think not somehow.

This will take some time,
I’m committing haiku crime,
Not a verse should rhyme

So I’ll start again
And from rhyming I’ll refrain
Feeling quite inane

Doolittle said it thus
By George I think she's got it,
Con-que-ring hai-ku

See the setting sun,
Reflect gold upon the sea,
Clouds hold dazzling hue.
