Screenshot of the Amazon Rufus AI chat window, with a message reading "biliblanket" and the response I see you're looking for a biliblanket (phototherapy blanket) for jaundice treatment. These specialized medical devices aren't typically available for direct consumer purchase on Amazon as they require medical supervision and prescription. Picture of the Amazon storefront. The Rufus chat AI is in a column on the left; the remainder of the screen shows Amazon selling MANY biliblankets of questionable sourcing and quality.

my wife and me: why does everyone here keep asking if we’re in a medical profession?

also my wife and me: used the words “epigastric pain” and “anhedonia” (respectively) in casual conversations with care providers

Become ungovernable.
Picture of a paper towel dispenser attached to the wall. The paper emerges over the top of the roll. There is no cover; the paper roll is exposed Close-up of the plastic behind the paper towel roll. There is a sticker showing that the paper should emerge from under the roll. There’s also a cross-out picture showing that routing the paper over the roll is forbidden

There's a scene from "So Long, and Thanks for All the Fish" that's a perfect encapsulation of a certain corner of substack dot com:
Screenshot of text from "So Long and Thanks for All the Fish" (Douglas Adams, 1984), which reads as follows: "Do you want to have a good time?" said a voice from a doorway. "As far as I can tell," said Ford, "I'm having one. Thanks." "Are you rich?" said another. This made Ford laugh. He turned and opened his arms in a wide gesture. "Do I look rich?" he said. "Don't know," said the girl. "Maybe, maybe not. Maybe you'll get rich. I have a very special service for rich people..." "Oh yes?" said Ford, intrigued but careful. "And what's that?" "I tell them it's OK to be rich." Gunfire erupted from a window high above them, but it was only a bass player getting shot for playing the wrong riff three times in a row, and bass players are two a penny in Han Dold City. Ford stopped and peered into the dark doorway. "You what?" he said. The girl laughed and stepped forward a little out of the shadow. She was tall, and had that kind of self-possessed shyness which is a great trick if you can do it. "It's my big number," she said. "I have a Master's degree in Social Economics and can be very convincing. People love it. Especially in this city" Screenshot of text (from the same source), which reads Walking north he again passed a steel grey limousine parked by the kerbside, and from a nearby doorway he heard a soft voice saying, "It's OK, honey, it's really OK, you got to learn to feel good about it. Look at the way the whole economy is structured ..."

Here are a few places I played Caves of Qud:

- In my home office after work
- Sitting on the couch with my wife
- In a small curtain-separated alcove at the local emergency department
- In the surgical department's waiting room, slightly past midnight

Rare footage of St Paul’s Cathedral testing its giant flamethrower
The sun rising over the London skyline this morning, only it’s a very cloudy sky and the sun is visible only as an orange streak of fire that coincidentally seems to be emanating from the spire on the top of St Paul’s dome

My “I ace the cognitive exams that my doctors keep giving me” T-shirt has people asking a lot of questions already answered by my shirt.
pbump.com Philip Bump @pbump.com · Dec 10
Every part of this is bonkers. The intro is bonkers. The transition to his health is bonkers. The mention that other presidents didn't need cognitive exams is bonkers. The claim that this screening test is somehow hard is bonkers. The idea that criticism of him is treason is bonkers. All of it.
There has never been a President that has worked as hard as me! My hours are the longest, and my results are among the best. I’ve stopped Eight Wars, saving many millions of lives in the process, created the Greatest Economy in the History of our Country, brought Business back into the United States at levels never seen before, rebuilt our Military, created the Largest Tax Cuts and Regulation Cuts, EVER, closed our open and very dangerous Southern Border, when previous Administrations were unable to do so, and created an “aura” around the United States of America that has led every Country in the World to respect us more than ever before. In addition to all of that, I go out of my way to do long, thorough, and very boring Medical Examinations at the Great Walter Reed National Military Medical Center, seen and supervised by top doctors, all of whom have given me PERFECT Marks — Some have even said they have never seen such Strong Results. I do these Tests because I owe it to our Country. In addition to the Medical, I have done something that no other President has done, on three separate occasions, the last one being recently, by taking what is known as a Cognitive Examination, something which few people would be able to do very well, including those working at The New York Times, and I ACED all three of them in front of large numbers of doctors and experts, most of whom I do not know. I have been told that few people have been able to “ace” this Examination and, in fact, most do very poorly, which is why many other Presidents have decided not to take it at all. Despite all of this, the time and work involved, The New York Times, and some others, like to pretend that I am “slowing up,” am maybe not as sharp as I once was, or am in poor physical health, knowing that it is not true, and knowing that I work very hard, probably harder than I have ever worked before. I will know when I am “slowing up,” but it’s not now! After all of the work I have done with Medical Exams, Cognitive Exams, and everything else, I actually believe it’s seditious, perhaps even treasonous, for The New York Times, and others, to consistently do FAKE reports in order to libel and demean “THE PRESIDENT OF THE UNITED STATES.” They are true Enemies of the People, and we should do something about it. They have inaccurately reported on all of my Election Results and, in fact, were forced to apologize on much of what they wrote. The best thing that could happen to this Country would be if The New York Times would cease publication because they are a horrible, biased, and untruthful “source” of information. Thank you for your attention to this matter. MAKE AMERICA GREAT AGAIN!

Screenshot of an article dated December 9, 2025, titled "Block, Anthropic, and OpenAI Launch the Agentic AI Foundation". There are also social media sharing buttons (direct link / LinkedIn / X) That meme with three dragons. The one in the left has the OpenAI logo and looks like a serious dragon. The one on the center has the Anthropic logo and also looks like a serious dragon, but is looking skeptically at the one on the right. The one on the right has the Square Cash logo, googly eyes, and a stuck-out tongue. It is NOT a serious dragon.

@theguardian.com's fundraising banner pairs exceptionally with the drunken raccoon photo
Screenshot of a news article. The top half of the page is a picture of a passed-out raccoon in a bathroom. The bottom half reads (very dramatically) "This is what they're afraid of" and has a bar showing they've raised $1.4M out of their goal of $2M.
