we're geniuses around here

I just had this conversation at work, with a man who used to work on the same team as me but moved to another department a couple of years ago.


He, looking at my name tag on my cube wall: "Did you change your name?"
Me, looking at my computer screen and typing: "Did I change...my name."
He:  "Yes.  I don't remember it being that."


I turned slowly to look at my name tag, thinking someone had messed with it and made it read Moron McWiggles or something.  As I turned, I said,


"No...did YOU change my name?"
"No.  I just didn't think that is what it is."
"What did you think it was?"
"I don't remember now.  But I did not think it was that."


I figured out he was talking about my last name, which has been the same for the past 29 years.  Always.


"Geez, and I thought our team's brains were fried tonight."  My team is all working late today.
"No, I just thought it was something else, but now I don't know what that is."
"It's always been that..."


As he started to leave, he said, "Well, at least it's short.  Five letters should be easy enough, right?"


Um..yeah.  Though apparently, it's not.
I wanted to ask him to pronounce my last name (I'm pretty sure he can't).  But I also want to be done working late and get out of here.
