Funny story: Back in 2006, I was working late into the night at a customer's site trying to fix a nagging technical issue. It wasn't happening. So I escalated to our team in Swindon, UK. I was greeted by a friendly voice on the other side of the Atlantic. As we were troubleshooting the issue, there was a lot of down time as the system did its thing.
To make the time pass, I asked the guy in Swindon where he's from in the UK. He said "Birmingham".
Of course, my ears perked up and I jokingly asked "Birmingham? Do you know Robert Plant?"
He replied "As a matter of fact, I do" I thought "What? He's got to be joking!"
He then went on to say how generous Robert is buying rounds for everyone at the pub and them two attending football matches together.
Apparently, my new colleague had been friends with Robert since they were kids!
