I was having trouble w/my computer. So I called Joe, the computer guy. Joe clicked a few buttons solving the problem.
He gave me a bill for a minimum service call.
As he was leaving, I asked, “So, what was wrong?”
He replied, “It was an ID ten T error.”
I inquired, “An ID ten T Error? What’s that . In case I need to fix it again?”
Joe grinned
“Write it down,” he said, “& I think you’ll figure it out.”
So I wrote it down.

I D 1 0 T

I used to like Joe:-(
