I'm sure you know this game but I haven't seen it on here yet.
Grab the nearest book. Flip to page 123. Find the fifth sentence. Type it here. 
Mine: "Lost and Philosophy: The Island Has Its Reasons". Only that my book is in Polish and its title is "Lost: Zagubieni i filozofia. Mroczna strona wyspy" - in translation: "Lost and Philosophy: The Dark Side of the Island". 
And the sentence is: "Kiedy Kate prosi Edwarda Marsa, by przestał ją ścigać ("I Do"), ten odpowiada: "Wiesz co, jeśli udowodnisz, że potrafisz usiedzieć w jednym miejscu, naprawdę gdzieś osiąść, przestanę cię szukać."
The translation is: "When Kate asks Edward Mars to stop chasing her ("I Do"), he replies, "You know what? If you can prove to me that you're capable of staying in one place, of truly settling down somewhere, I'll stop looking for you."
