I'll put it under the "Folklore" section. I'm guessing it's the thread that never ends/won't go away.
You're pretty close. Threads themselves come to an abrupt end at post #65534. (We know, because we took our very first thread to that point.) The mods don't like that, so we now move to a new Zot thread (it's always a Zot thread) at the end of every month, at which time we've accumulated 4000 to 6000 posts.
