I was idly searching for pictures of Beer after my trip earlier today, and came across a magnificently useless but diverting web site. Not only were all the paintings I clicked on unreviewed and unavailable, but the Testimonials page contained this unintentionally funny gem:
"John reminds me of a swan
Across the sky he flies so high
Like one of the greatest birds in the sky.
He's fancy free and ready for tea
He looks around on the ground
For sea worms swimming around.
He sees other birds flying high in the sky
Singing their song as they fly along... "
It goes on - but I won't 
Well, it beats watching the *&%$£@* Olympics...

One of the things I have found when teaching children to write verse is that most will place rhyme way above rhythm and sense. A pet hates is 'did go' instead of went.
On the other hand children will take note of what you say, while adults just act hurt if you suggest that maybe they have a bit to go before they rival Shakespeare, or that just a knowledge of the technical structure of classic poetic forms could help.
My Uncle Peter, who was actually rather a good poet, was inclined to suggest that with a bit of work he might break into the greetings card market. Such modesty is rare.
