Do you know Harold--I do

I was having trouble with my computer. So I called Harold the computer guy, to come over. Harold clicked a couple of buttons and solved the problem.

He gave me a bill for a minimum service call. 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?"
Harold 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 Harold.............

I remember a while ago my then boss had a problem with his desktop "not working properly" - I didn't have time to look at it so I called Harold in to have a gander - his report later was that it was a PICNIC error and was now fixed - I of course had to ask what a PICNIC error was - Harold made me promise not to tell our boss ..........

Problem In Chair Not In Computer

I still like Harold
