Let's see..
Sometime around early 2001, after the election.
Dropped into the Dimensional Doors thread, and we went over to another thread to weird people out.
(Someone had made a wisecrack about one of us.)
So we kinda were bad.
(Mods appeared afterwards.)
But, making it short, I was cracking a joke and got a response from my group, and someone took offense to the response.
They didn't recognise familiarity in the response.
Feels like a lifetime ago.
*chuckle*
