Steven Pinker: Words and Rules

This book is about nothing but regular and irregular forms of nouns and verbs. It is amazing what can be learned about the human mind from this duality. While this book is not an easy read as "The Language Instinct", it is much more detailed. Where "The Language Instinct" is an overview over modern psycholinguistics and presents lots of different facts in a kind of anecdotal way, this one meticulously examines a single feature of human language, much closer to the actual science, giving lots of detail about the experiments that are the basis of the presented results. Certainly less entertaining, but also offering deeper understanding of its subject than the "Language Instinct".

Reinhard Ulbrich: Spur der Broiler – Wir und unser goldener Osten

A satirical retrospect of the life in the GDR. Lots of jargon and detail that are probably best appreciated if you have lived through that time yourself; while I have not, I have apparently learned enough about it from friends and acquaintances to still enjoy it. Not outrageously funny, but entertaining.
