"Little Willies" were common in the US back in the 20's and 30's maybe? I learned several from my parents and grandparents.
Little Willie, dressed in sashes
Fell in the fire and burnt to ashes
After while the room grew chilly
Because no one wanted to stir up Willie
Willie playing by the track
Didn't hear the engine squeal
Now the train is coming back
Scraping Willie off the wheel
There's another varianton the train track theme whose last two lines are:
The neighbors were surprised to find
How travel broadened Willie's mind
My mother's favorite: Little Willie's dead and gone
We'll never see him more
For what he thought was H2O
And for silliness, I always liked this Robert Frost poem:
I stepped on the toe
Of an unemployed hoe
It rose in offense
And struck me a blow
On the seat of my sense
I must say it dealt
Me a blow that I felt
Like malice prepense
Now wasn't there a rule
that a weapon
should be turned into a tool?
But what do I see?
The first tool I step on
Turns into a weapon.
