Netmemething: The Nearest Book

From the honorable Col. Rebert's blog:

• Grab the nearest book.
• Open it to page 56.
• Find the fifth sentence.
• Post the text of the sentence in your blog along with these instructions.
• Don’t dig for your favorite book, the cool book, or the intellectual one: pick the CLOSEST.

I'm going to assume that I shouldn't reach through my desk, which means that the correct sentence is:

""What may I say to you?" I said. "Perhaps you do a good thing. I hope so.""

Though there are rather a lot of quotes, and I'm not certain how those interact with sentences... most peculiar. It would've been simpler had I just read something from a math-book instead.

(It's from The Great Book of Amber, by the way, by Roger Zelazny. Compilation of all (?) 10 books in the Amber series of novels. Quite good, at least the first five; I've never quite gotten around to starting the latter half of the book.)

Adversity is the spice of life, they say.

At any rate: now, for a rebus. (The first thing that came to mind.)

- man- d/dx

Enjoy! (You may wish to check the url for the third and fifth ones, they're a bit tricky probably. Especially the fifth, which I'm probably going to have to apologize to someone for.)

EDIT: Images aren't working properly for me. Should be aligning in rows, but they aren't. For reference, the first two images form the first word, and the rest form the second.
