Nonsense Poetry
Here's a poem I still remember from a British collection of nonsense poetry called "Oh! What Nonsense!":
Way down South where bananas grow,
A grasshopper stepped on an elephant's toes.
The elephant said, with tears in his eyes,
'Pick on somebody your own size!'
If I recall correctly, the poem was attributed to one 'Anonymous'. If I recall incorrectly, all rights reserved, blah blah blah.
Oh, and my suddenly quoting this poem has nothing whatsoever to do with some challenge on the internet.
