Im with you! The Golgafrinchan government bits of The Restaurant at the End of the Universe and the opening of Life the Universe and Everything are my retreats when things are rough, but the entire series is amazing!
Oh and I should say, I enjoy all the different Adams adaptations(even the movie!), but my personal favorite that I think is less well known: the HHGG audiobooks read by the author. The timing and phrasing of Douglas Adams was truly marvelous!
