Happy Fried-Day

I was having trouble with my computer. So I called Richard, the 11-year old 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, 'What's an ID ten T error?'
Richard grinned. 'Haven't you ever heard of an ID ten T error before?'
'No,' I replied.
'Write it down,' he said, 'I think you'll figure it out.'
So I wrote down:
I D 1 0 T
I used to like the little shit.
