Keyboard Gnomes

And I don't mean this kind.
What I mean, is that every time I go to use my number pad on my keyboard, the number lock button is off.
I don't have proof, but I know it's keyboard gnomes. Or trolls. It could be trolls.

I must booby trap my computer.

Of course, I'll forget all about the barbed wire trappings and probably lose an hand.
And it'll be all those damn keyboard gnomes' faults.

LEAVE MY KEYBOARD ALONE!
