Hurrah Hurrah! The First of May!

This is my oft-repeated tribute to the First of May.

Where Do They All Come From?

A little green man
in a fluffy yellow hat
underneath the rim
of a toadstool sat.

He twirled his finger
and he twitched his toe,
he looked at his watch
and said "Time to go!"

He jumped to his saucer
and quickly spun away
but he left his yellow hat
on the field of May.

Marguerite Louise Monette
