I'm happy I finally read this, it was fun! While I think that a lot of people probably had even more fun with it, I do see how it became such a classic. It's delightfully absurd and even though it is full of nonsense, I feel like it makes some amazingly accurate observations about humans. And something I took from it was how unimportant humans are if you see them in relation to rest of the universe, which was nice to read, because humans tend to think they're the most important thing that ever existed. 
I also have a lot of respect for people who can think in these absurd ways and construct a story around these thought processes. I would like to know how one finishes a story that includes this many random anecdotes and sentences. And how one can develop this sense of humor; I feel like it is very rare and inimitable.
