A lot of my favorites are already mentioned here, like HHGTTG, Pratchett, Vonnegut, Simmons, so here a few others, since I don't want to sound repetitive (in no particular order):
* Winston Churchill - The Second World War
* Walter Moers - The Thirteen and a Half Lives of Captain Bluebear
* Scott Adams - The Dilbert principle
* Charlotte Chandler - Hello, I must be going
* Frederick Brooks - The mythical man-month

sympatico hehheh

Hello, I must be going.
I cannot stay,
I came to say
I must be going.
I'm glad I came
but just the same
I must be going.

I'll stay a week or two,
I'll stay the summer through,
but I am telling you,
I must be going.

Groucho Marx – Animal Crackers, 1930
