Ha Shu'al B'Lool Hatarnagolot - Ephraim Kishon. funny from page one & my first contact with the strange world, rules and absurdities of political systems (couldn't find the english title, sorry)

The Mythical Man-Month: Essays on Software Engineering - Fred Brooks. introduced the concept of an essays to me, and that the software wolrd is really as strange as i always felt

of my favorite books, those are probably the two best fitting into HN, since they enlighten in some way :)
