Group Discussions about Hitchhiker's Guide

The other day I found some groups about Douglas Adams and the Hitchhiker's Guide to the Galaxy on Google and Goodreads.  Part of the way I want to research Adams' skill with comedy is to connect with others who love his works and hear what they have to say about it.  So, I used the discussion sections on these groups and posted this to them.

"The first time I read Hitchhiker's Guide, I was blown away by Adams' uncanny ability to write comically. His books are so memorable largely because of Adams' skill with humor and his great one-liners.
What do you think? How does Adams do it? What is it about his writing that tickles our funny bone every time?"

I have put this question to three different Douglas Adams fan groups now (it has been a challenge to find good active fan pages. I mostly find blogs and other types of websites).  This morning I had some emails alerting me that I've received a couple of answers to my question.  Both have mentioned reasons why they find Douglas Adams so funny and have given me new insights into his writing style.  I can't wait to see what other people have to say.
