Book-wise, there’s not much comedy science fiction that I’m aware of
Really, Cohen? You're saying this on a podcast called Geek's Guide to the Galaxy, and you don't think that there might be a pretty obvious example that you may have possibly overlooked?
I get what you're saying (Hitchhiker's guide! obvs
)
As it happens, the host of the podcast has complained along similar lines. There is HHGTTG, but beyond that, there isn't very much.
Writing this out now, though, I wonder if the ratio of comedy:non-comedy is more-or-less the same in sci-fi as it is in general fiction.
