It’s an overdue open thread

We’re long overdue for an open thread, so here it is.  Now you can post that otherwise off-topic comment that I deleted three days, three weeks, or three months ago.  Feel free to talk about whatever you like, from light cones to Indiana Jones, Duns Scotus to the current POTUS, Urdu to Wall of Voodoo.  Just keep it civil and classy.
