[rushing into the Situation Room clutching a sheaf of papers] Change of plans I'm afraid — in a poll 52% described Cuba as "the big one that Florida points to" and Panama as "the little neck bit", which our lawyers reckon would stand up in the International Criminal Court. Where else have you got?

[the morning after I conduct air strikes on North West Essex] There's a lot of noise from people who couldn't find Saffron Walden on a map yesterday
As someone who was very very Twitter poisoned, it's wild to see Kemi open a statement on a hugely significant international incident with the preface "lots of people on the internet are wrong!!!!1!". It's time to log off, for the love of god.

It's all very well saying "don't give out your name" but it's not as simple as it seems, as explored by Constance Cooper in a related field

As a consequence of my extremely high degree of personal moral virtue I developed an innate knowledge in utero of every bad deed committed by any person or institution throughout recorded history. If someone has to learn these things via exposure to facts they deserve nothing but contempt

The same issue arises in philosophy of cooking: if a recipe says to cook something for N minutes and that “meanwhile” you should carry out some other steps, is it true in the fiction of the recipe that those steps can be completed within N minutes? (no, don’t be daft)
I think this is genuinely an important question in philosophy of fiction, and it has the same answer as "if a story reports all X words of a dialogue and tells you it took m minutes, is it true in the story that the characters spoke at X/m words per minute" (no, don't be daft)
The James Bond discussion reminds me of a long Discourse we had in grad school re whether cozy murder mystery shows (think Murder She Wrote or Midsommar Murders or Detective Conan) are meant to literally have the crime rate implied by on screen murders.

Just watched the new Knives Out and I think it's really important you know that the scene in the Seminary's Gym is filmed in the same place Rick Astley filmed the music video for Never Gonna Give You Up.
I saw the window tracery and immediately made my friends pause the film so I could tell them.
