Tech Support: “What version of Windows are you running?”
Customer: “I got the computer in 2003, so I think it’s a Windows 2003. Or maybe it’s a Windows 2004? I got it late in the year.”
Tech Support: “Um, ok.”
Customer: “Is that wrong?”
Tech Support: “No, no, that sounds about right. Tell me, would you know what service pack you have for that?”
Customer: “Well, when I got to the register, the young man who rang me up said was about the 5th person to buy it. So it might be service pack 5.”
