Have you ever found yourself incorporating fannish running gags into the world of Collinsport, that you carry around in your head? In my case, it's jokes made over the years on the captions and episode discussion threads. By now, I've heard so many jokes about Professor T. Elliot Stokes being some colossal "cheese pervert" (if there even could be such a thing...) that I have to remind myself that he may not have mentioned cheese more than once. At some point, I'm going to forget that there was never really such a place as the "Tool Shed Bar & Grille", MB's running joke in the fill-ins area. I see Sarah Johnson, and I think of a barely-repressed hysterical obsession with mayonnaise. That area of Maine must always deal with strafing runs from Velvetian space ships. The Old House staircase, don't fence it in....!
What strange fan-canon things like this exist in Collinsport, for you? They don't have to be jokes. A lot of fannish theories get proposed, to explain this or that, and we can get used to thinking of them almost as if they were seen onscreen...
