Python is a great example.
In its defense (and Adams’) there’s a forth category: jokes (even problematic ones) that become funnier due to changes in society.
Graham Chapman’s bug-eyed ranting authority figures, for example. They used to lampoon a particular echelon of brutally stupid reactionary Briton that were then military and corporate boardroom archetypes, and at a certain remove from everyday life. But their modern euivalents are now running the country without any supervision at all from the civil service or (at least this week) from voters. So the chance of running into a petit chapman on the train or in the pub is a form of dread that’s been successfully rebooted.
