Jokes are a way I have of handling psychotic urges.  I prefer to speak
   nicely at all times, but jokes happen.
   Here's one about real life.

   Karl walks up onto stand up comedy stage, takes mic.
   "I joined a cryptography list and nobody on the list was using
   cryptography!"
   Canned uproarious laughter!
   "Not only that, I wasn't even sure why I got on the list, could barely
   control my behavior, and this was after I had been overtly
   brainwashed!"
    Canned uproarious laughter!
   "On the list, nobody seemed to really know about cryptography.  People
   would talk about technologies that were a decade out of date, use
   systems and setups nobody on the list would use ..."
   A small pause.
   "Sorry, that was just a build-up to something, but suddenly my
   brainwashing kicked in and I suddenly don't remember what point about
   this list I was trying to make."
   Canned uproarious laughter!
   "What's crazy is that when I read the list and post to it, I actually
   believe it's the real thing and that the people posting to it actually
   know about it!"
   Canned uproarious laughter!
   "Then I keep posting to it, barely able to guide my behavior, certainly
   without any plan, as if nobody on it knows anything about it and needs
   help understanding its culture, which personally I have almost no
   experience with!"
    Canned uproarious laughter!
   "I looked up the history of this list and it looks like it was
   systematically destroyed by huge swaths of hired trolls.  Maybe I
   subconsciously assume that everyone I'm talking to is one now."
   Canned chuckles, some canned groans.
