spoilers, but only in the minorest sense of the chapter titles being revealed, and their relevance discussed.
So, all the chapter titles in this book are a bit weird. Some of them have an easter egg quality, in that they refer to something, or have hidden significance that you might not see at first glance. If you can figure out why a specific thing was chosen for a chapter title, please put it in this thread
Chapter titles, with any significance I was able to identify
1: Chapter 2 - because Alcatraz was too stoopid to include chapter 1, which is a shame because it has all the stuff that would make the book non-confusing
2: Chapter 6 - it's a relief he skipped all the boring stuff from chapters 3, 4, and 5
3: Chapter pi
4: Chapter 4 1/2
5: Chapter 42 - The ultimate answer to life, the universe, and everything from The Hitchhiker's Guide to the Galaxy
6: Chapter 144
7: Act V, Scene III
8: Chapter A+
9: Chapter No!
10: Chapter 1010 - 1010 is 10 in binary, which matches up with the fact that it is the 10th chapter
11: Chapter 24601 - Main character's prison number from Les Miserables
12: Chapter 070706 - Probably a date (July 7th, 2006) but I don't know why
13: Chapter 6.02214179 x 10^23 - Avogadro's number, a constant having to do with measuring the number of atoms or molecules in a substance
14: Chapter Four Teens and a Pickle
15: Chapter 8675309 - The phone number in the popular song "Jenny". Lord have mercy on anyone with this phone number in real life
16: Chapter 16 - Umm, this actually looks like the regular chapter number. Am I missing some kind of trick here?
17: Chapter NCC-1701 - Or, more completely, USS Enterprise NCC-1701, the name of the ship in the original Star Trek series
18: Chapter 4815162342 - 4, 8, 15, 16, 23, 42 is the sequence of numbers that appeared in the television show Lost. People trapped on an island thought they had to type these numbers into a computer every so often or the world would end.
19: Chapter ???
20: Chapter infinity
21: Chapter infinity + 1 - for those of you not in the know, this number is the same as infinity. You can't get any bigger than infinity
