The submarine Captain ordered a standard sub.

There in started his problems, after he set sail.

Twas on his maiden journey

That the systems started to fail.

The crew were utterly petrified

For at 500 fathoms sprung the leaks

The crew were beside themselves

As over tannoy, the Captain speaks.

“Men I’m awfully sorry.

It’s my grammatical error that’s caused out fate

I’m such a foolish Captain

And now it’s far too late!

For when I ordered a standard sub”

To the crew he pandered

” I didn’t write standard sub

Instead I wrote substandard”
