computer trouble

I was having trouble with my computer.

So I called Richard, the 11 year old from next door whose bedroom looks like Mission Control, and asked him to come over.

Richard 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 stupid, but nonetheless inquired, 'An, ID Ten T error? What's that? In case I need to fix it again.'

Richard 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 used to like the little sh*t.
