Internet Junkyard #18

My aunt sent me this and enjoyed this:

As we Silver Surfers know, sometimes we have trouble with our computers. I had a problem yesterday, 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:
ID10T
I used to like Eric, the little shit.if you're not a Senior yet then send this to one...
