Hi, my name is Fred the mouse
And I am Karl the scanner's spouse
We all live in our users house
At times we groove with Scottish Grouse

Attached to Grace, our boss in charge
We all work hard and run at large
To make our user smile and happy
As long as user's work ain't scrappy

'Cause when this happens Grace runs mad
She starts to hick-up which is bad
For me and Karl - and Ann, the mainboard
Times get rough and none are bored

We're bound to lose built up connections
When user wrecks our output sections
Geez, us hardware dreams of freedom
To vouch for users gate to wisdom

We're not just simple hardware add-ons
Without us, you users end up morons -
So, dear friend: watch out and care
Before Karl and I and others tear!
