I wrote a sonnet.

An Ode to A Man's Best Bonnet.

One autumn’s evening, in my hut
I had an idea which stirred my gut
Upon contemplation, I decided that --
That I would seek out my favorite hat

The hatter’s shop I did first try,
But the selection of hats did make me cry.
Not a one would I well have died in,
Not even a fine bowler could I have pride in.

After this failed and sad attempt
I did visit a store so very unkempt.
Inside I found one for but thirty bob,
A shiny top-hat would do a sterling job.

In retrospect, and upon deciding,
I find my true favorite is still in hiding.

[It doesn't have Shakespearean rhyme sets, but it does meet the requirements for a sonnet.]
Bye.
