I usually don’t find quips or piss takes on social media very funny. Reform types and their AI leave me cold and Bluesky seems to have a cohort of unfunny left wing ‘satirists’.
But that tweet is genuinely amusing. Humour of that sort needs some foundation in reality to be funny. And Starmer’s reduced his position so badly by always apparently being left unaware of important facts, by relentlessly dumping on people, and by being morally outraged after the event, that the joke works very well.
