The most repulsive thing about the crimes taking place in the Caribbean is they’re doing it as a troll — this isn’t a desperate conflict with a mighty enemy or an emotional reaction like after 9/11, they’re doing it in order to be called out so they can call their enemies soft.

"According to the World Bank, the deadliest place in the world to be born is Niger. More than one child in 10 there dies before age 5. Those are better odds than the children of 17th-century English kings had." theargumentmag.com/p/medieval-kin…

Louis CK (and in particular his FX show, Louie) is like the human embodiment of Don Draper’s line: “It will shock you how much it never happened.” Just airbrushed out of the histories of the golden age of TV/best show lists. nytimes.com/2025/11/21/art…

Lot of people fairly questioning whether AI slop is actually worse than journo slop, but the bigger risk imo is that culture gets trapped in amber because it's trivially cheap to re-slop 2010s training data and nobody bothers writing for free because you're yelling into the void

Per Graphite, 52% of the articles written online are now written by AI. The Slopocalypse is here.

You wouldn't believe the number of times I've narrowly escaped death as an agent of a covert, black ops squadron. But my little nephews would, and that's why I'm looking forward to Thanksgiving.

Allowing Trump to transition full time into producing mediocre buddy comedies would, frankly, be a win for the Republic.

I teased this last night in What I’m Hearing but now confirmed: Paramount WILL release Rush Hour 4 after prodding from Trump on behalf of Brett Ratner. Distribution deal. Producer Tarak Ben Ammar is lining up financing. Get ready for the dumbest possible state-controlled media.

Fun fact. The terms of this series can be arranged to sum to any real number.

Make it a scandal! Write articles about it, then ask about the articles in a press conference, then write articles about how you didn't like the answer. Send out push notifications for the op-eds about those articles. A scandal is whatever the media wants it to be.

In a normal administration this would be a huge scandal
