(From friend's e-mail)

I was having trouble with my computer.

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

David 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.'

David 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 shit.
