One Tuesday, a few years ago, I received a courtesy invite, by e-mail, to a meeting that I might be interested that afternoon. I had time, and it interested me, so I wandered over to the meeting room at the appointed time, but no one was there. Puzzled, I returned to my desk and looked again at the e-mail. Turns out the e-mail had been sent two weeks earlier, and had taken 2 weeks to travel about 100 feet!

If I recall correctly, that was the same company at which the e-mail administrator sent me an e-mail to tell me my e-mail wasn't working!
