Guerrilla tactics (Score 2, Interesting)

This article reminded me of something my buddies and I have been doing for some time.. We will buy a book (normally a "subversive" of thought-provoking one) and paste a piece of paper inside which reads something like "This book has been given to you as a gift, but you can't keep it. When you finish reading it, you must give it away to somebody else so information can keep flowing". Then we give the book to someone, or leave it at a public place. Thus we don't infringe any laws, because giving away your own purchased stuff as a gift is perfectly legal, and many people can benefit from a single book. Besides, we find it quite inspiring.. ;)
