Lock & Key Poem

I've been reading some Shel Silverstein poems and was inspired to write a poem of my own. In case it's hard to read from the drawing, it says:

I may or may not have committed a crime,
Now I'm under lock and key.
I'm wound around and tightly bound
So that I can't get free.
I'm locked up and I'm locked down,
And I'm locked left and right.
This chain is a pain,
This straight jacket is insane
And these ropes are pulling
Too tight.
