Novel in a Haystack
Q A friend tells you someone stashed a $100 bill in a novel in the neighborhood library. The friend doesn't know the title of the novel but goes on to say that the money is between pages 201 and 202 of the unnamed novel.

With this information, do you ransack the library looking for the right novel and the money, or do you laugh off the whole matter? Why?

A Save yourself a lot of time by just laughing off your friend's report. Don't bother looking for the novel. Every professionally made book numbers its pages by using odd numerals on right-hand pages and even numerals on left-hand pages. No one could have put anything between 201 (a right-hand page) and 202 (a left-hand page)!
