Here's my first (and onl)y attempt:
Little Willie was a brat
Little Willie hurt his cat
It was his sister's hair he yanked
On his bottom he got spanked!

This is a GREAT forum for letting loose the BEAST that lurks within. Everyone has one (or more), some are just on shorter leashes.

These first appeared in the late 19th century under the heading "Ruthless Rhymes For Heartless Homes" and featured a boy named Billy. One of the more famous quatrains: 

Billy saw some dynamite.
Didn't understand it quite.
Curiosity never pays.
It rained Billy seven days.

here are several of mine:


Willie took the baby's head
from the pillow on the bed.
Knowing Willie, we're quite sure
he didn't take the rest of her.

Willie's friend has leporsy.
Willie visits constantly.
Lots of friends has Willie got
but only one of them can rot.

Willie, high on LSD,
said Baby looked just like TV.
Look at Dad and Mother grin!
Willie plugged the baby in!

Willie got in Daddy's car;
didn't drive it very far.
Mother got in Willie's way.
Her funeral is Saturday.

Little Willy?  I thought you were talking about something else there for a second.  Shame on me.

Seriously, I'd never heard of this form.  I've seen poems like those you posted, but I didn't realize they had an *official name*.

Thanks Jess.
