Computer Trouble

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

Eric 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 Eric...

I know. I make those errors all the time. Would this joke be better with the last two lines omitted?

Doug again. Is he trying to tell me something?
