Brainstormfront has posted the story of Jeff Grubb day over on his site. I have nothing to add except that I got off easier than DRAGON editor Roger Moore. In my case, a couple in Texas tried to get admission to a convention for free because "they were Jeff Grubb". A quick phone call straighened matters out (and set the ball rolling for Jeff Grubb Day). Roger was less fortunate - he was scheduled to attend a convention on the West Coast, but had to bow out. A fan stepped in to imitate Roger for the weekend, sitting on panels and answering questions as if he was Roger Moore, and THEN wrote us, volunteering to serve in the future as "The West Coast Roger Moore."
Yes, its a whacky world where people impersonate Game Designers.
