This poem came to me in a few lighter moments. Watching my dog playing.

A puppy plays a funny game
As It walks on playfully ahead
Abruptly it may turn around
And try to catch its tail

And as the tail moves around
Along with the bum
It will wiggle and wiggle
And struggle and bend

Distracted by a sound
It will abandon its game
To walk ahead for a moments few
Till it again sees its tail
