I think it's plain, I think it's clear
What is meant, by this poem here.
It is not crime, that Dahl did hate
But all those things, which begin to grate.
No, not muggers, nor robbers nor thieves,
But all those irritating little pet peeves.
From people sitting picking noses
To tangled up garden hoses.
Grinding teeth, and snapping jaws
And all unpleasant character flaws.
Whether you agree or no
It's near time for me to go.
But before I do depart
I've one last thing to impart
Dear friends, we surely all agree
There is no poet quite like he.
In this poem i think he relates chewing gum to other crimes. I don't think anyone would hate chewing gum that much and he was sending a message about those who do crime are bound to have a sticky end. He might just really hate gum though!
