Chronic Suicide Support

I was having trouble with my computer. So I called John, the 11 year
old next door whose bedroom looks like Mission Control, and asked him to
come over..

John clicked a couple of buttons and solved the problem.

As he was walking away, I called after him, 'So, what was wrong?

He replied, 'It was an ID ten T error.'

I didn't want to appear to stupid, but nonetheless inquired, 'An, ID
ten T error? What's that? In case I need to fix it again.'

John grinned. 'Haven't you ever heard of an ID ten T error before?''

No,' I replied.

'Write it down,' he said, 'and I think you'll figure it out.'

So I wrote down: I D 1 0 T

I've used that line a few times working with people who know just enough to be dangerous.  I don't use it with paying customer though!

Oh man, we usto always use the ID ten T error line when we would call the service station when I was an alarm installer. It's one of my favorites.

I'm pleading complete ignorance there.. Never heard of it and wouldn't know it if it were printed on the front of a dump truck as it was about to run over me.
