ID ten T error

Judy, the editor of a trivia publication, was having trouble with her computer. So she called Dave, thecomputer guy, over to her desk.

Dave clicked a couple buttons and solved the problem.

As he was walking away, Judy called after him,"So, what was wrong?"

And he replied, "It was an ID ten T error."

A puzzled expression ran over Judy's face. "An ID ten T error? What's that..in case I need to fix it again??"

He gave her a grin, "Haven't you heard of an ID ten Terror before.""No," replied Judy."Write it down," he said, "and I think you'll figure it out." She wrote: ID10T
