The aliens' plans were, if I remember right, posted for display in a nearby star system, with a similar 'it's your own fault if you didn't bother to go look' justification.

The indie book series Dungeon Crawler Carl, which is entirely unlike Adams' work in most ways but clearly takes some inspiration from the malevolent absurdity on display, uses a similar premise where the demolition-causing aliens let the pharaohs know 40,000 years ago and that serves as sufficient legal notice.

... almost, but not quite, entirely unlike ...

The best sentence in the entire book

I think it's tied with "The ships hung in the sky in much the same way that bricks don't."

I think both of those lose out to the discussion of "grammar in the context of time travel".

this is the stupidest debate that I'd be willing to read an entire transcript of.

Further similar vibes: the DUST short film "Final Offer": https://youtube.com/watch?v=rv8kOzRZK8g

> little nitpick but it’s where the local council put the notice about bulldozing his house.

True, but later on we find that the aliens pulled the same trick with the notice to demolish earth.

It was hilarious what the city council did to Arthur, it was even funnier when a few pages later we find you that the Vorgons did the same thing.

Entirely unnecessary nitpick: they are Vogons. Had me questioning myself for a moment if I'd consistently misread their name!

this could have been quite likely since it wasn't until I was about 18 years old that I realised Kawaski motorcylces were in fact Kawasaki motorcycles!
