This is the story Ellie-Mabel
Who licked the gum under the table
(As I’m sure you’re all aware
Naughty children stick gum there)
At first it was just a game
To amuse her until playtime came
But then one day disaster struck
Ellie-Mabel’s tongue got stuck
Onto the gum so white and sticky
(Serves her right for being icky)
So there she lay under the table
Till the teacher said “Where’s Ellie-Mabel?”
“HELPTH BY TONGK ITH THUCKK!”
Cried the unfortunate little schmuck
The teacher looked all around
To find out who had made the sound
She searched the classroom, edge to edge
Even upon the window ledge
She rummaged under flower pots
And other such unlikely spots
Then finally looked under the table
Where she found Ellie-Mabel
Dangling in mid air
As her tongue held her there
“EEEK” the mistress let out a screech
“How am I supposed to teach
A child such as Ellie-Mabel
Who sticks herself under the table?”
Her wild classmates were delighted
To see their poor teacher blighted
They banged on desks and jumped on chairs
Thrilled by the entirely awful affair
(Ellie-Mabel would have joined in too
But gum makes an exceptional glue)
“We’ll cut her down” teacher declared
Ellie-Mabel started to get scared
“Blood will splatter and guts may fly
But she needs to learn to multiply
And for that she needs to be able
To complete her sums upon the table
And not by dangling underneath
Or gnawing at gum with her teeth
In all of my years as a teacher
I’ve never met such a wayward creature
And who has raised this little dolt?
It must be all the parents’ fault”
The teacher marched towards the door
Off in search of a large-ish saw
While she was gone the classmates pulled
Upon the poor little fool
They grabbed her legs and made a line
The one in front then gave a sign
The children hauled with all their strength
Stretching her tongue to an enormous length
Until at last Miss Ellie-Mabel
Was freed from the gum under the table
Moments later the teacher returned
And what is that lesson that has been learned?
Never lick the gum under the table
Or you’ll end up just like Ellie-Mabel
Who is a bit more cautious than before
Now that her tongue drags on the floor
This is a funny poem. Children, especially, will enjoy it. Especially the "icky" aspect of it. Children love that sort of thing. (That's the positive critique...)
BUT - as someone else pointed out on another shared poem - you either go free verse or you follow the rules of rhyming and scanning. Your rhymes are mostly good and sometimes surprisingly inventive, but you need to work on the scanning.
A good rhyming poem (ESPECIALLY one for children) should chug along with a steady rhythm. You have lines with too many syllables and others with too few. They break the rhythm. It would be worth working on those.
A tip: get a friend to read this out to you, and pay attention to where the rhythm isn't quite right. Then you read it out to the friend, and see if they notice any "bumps" that you missed.
