OneOfMany and 42: A lot cleaner than Hitchikers Guide. Except that one book with that one song about a hedgehog. And there is a metric ton of innuendo, especially the witches and Wee Free Men series.
There’s also quite a bit of apikorsos in there, but it’s presented in a fantasy oifen. (One book, for instance, deals with the god of evolution who happens to be an Atheist.) And, as I always say, if you think that reading a book is going to change you beliefs in HaKadhosh Baruch Hu, you have many more problems to worry about.
All in all the books are hilariously funny.
