While people have referenced “42” to death, not many people I meet have seen (or read, or listened to) one of the many incarnations of The Hitchhiker’s Guide to the Galaxy. The 1981 show had production values roughly on par with Doctor Who episodes, but with wonderfully charming animated segments representing the book’s various entries.
My dad taped it off PBS when I was very young and, when I was about 10 or 11, said “here, watch this.” It’s great. (He also has the first Stooges LP and never bothered to do the same thing - I had to find out about that one on my own.)
Anyway, if you have a half hour to kill I suggest watching the first of six episodes of the TV show (and the rest, if you like it). The radio dramas are also fun (and now span all 5 books), plus there are also novels for those of you who are still inclined to read. If social media people or message boards haven’t made you hate it before you’ve seen it (see also: Army of Darkness, Monty Python, Firefly, Doctor Who) I suggest giving it a try. I’m not saying it’s great - but it is one of those rare instances of something that’s sci-fi and funny. Not “ha ha R2-D2 beeped” or “Spock said something snide” but clearly inspired by actual comedy.
