I had a problem with my computer yesterday, so I called Eric, the 11 year old kid next door.
Eric clicked a couple of keys and solved the problem. As he left, I asked, "So what was wrong?"
He replied, "It was an I D ten T error."
I felt stupid asking, "What's an I D ten T error?"
He asked, "Haven't you ever heard of that before?"
"Nope."
Write it down. You'll figure it out."
So I wrote down "ID10T."
And I used to like him.
