The M.R.I

I need an M.R.I,

A scan on my head,

I'm feeling quite nervous,

As I look at the bed!

This won't hurt a bit,

The doctor told me,

It'll take half an hour,

And then you can flee!

I lay on the bed,

Earphones are put on,

Cos, the machine is quite noisy,

I don't want my hearing to be gone!

Then a helmet,

It covers my head,

But there's a little mirror,

So I can see the world from my bed!

Into the tunnel I slide,

The machine makes a groan,

Eek, this is it!

I inwardly moan.

Oh, the sound is so loud,

With bangs and a thump!

I'm really on edge,

With each one I do jump.

The time marches on,

Surely the end it is near?

I want to go home,

Want an end to this fear!

The job is now done,

I'm released, I am free!

I go and get dressed,

And then home I do flee.

Now there's a wait for results,

It'll be quite a strain,

But I can't help but wonder,

Did they find I had a brain?
