I'll chime in with Stranger in a Strange Land...provokes thought before you even open the cover.

I believe that in this fast paced world, a title has even more to do with a work than anything else. For example, how I came to make this post. 
Taking a study break, I was reading some facebook posts. A friend put up an interesting article talking about choices made. Then I noticed another interesting looking article about the pros and cons of having children. This post brought me to finding this website. After reading several posts I decided to join this website. Immediately after joining... I saw your title and I clicked. 

Now... I will admit, I did actually WANT to learn about how to light a castle, hence why I clicked, but I am not disappointed. With a clever title such as the above, I expected one of two things; I will either learn how to light a castle along with several other bits of trivia that I shall likely never have cause to use, OR I might be entertained by a cleaver author. Thus a clever title enticed me to read the post. 
In a bookstore, my thought process goes: if a title is clever, I will pick up the book. Depending on how clever the title is will determine if I look at the first bit of real writing or if I flip to the center and pick a selection at random. Should that selection also be entertaining or educational, I might buy this book. 

As a graduate student, reading for fun is a VERY involved decision that MUST NOT be taken lightly. To purchase a book to read in your *laugh* spare time more often than not equates to a waste of money. However, if the title is catchy enough and the chapter is witty enough... it just might make the cut. 

That's why the last book I read was by Christopher Moore and was titled "Lamb: The Gospel According to Biff, Christ's Childhood Pal" which I would recommend to anyone.

Stranger in a Strange Land still affects me even though I haven't reread it in more than 20 years. It seemed to be the guidebook to the 60s--and beyond. I still try to 'grok' things.
