So, in the midst of the stress week over the upcoming job interview, I get an email from my current employer saying something to the effect that since my last day of employment is Friday, just make sure I fill out my time sheet one last time and it'll be processed next Tuesday.
Huh? HUH??? WTF?

No answer from anyone for hours. My supervisor finally got out of meetings and was shocked and mystified, too.
Then the woman from my employer finally calls back. "Oh, we have the wrong John. Sorry."
That's about it. She repeated it three times. But that was it.
Sorry.
