What book titles can lead to

Freakonomics led to:
1. Slackonomics
2. Freedomnomics

What are other possibles?
1. The World Is Flat: Get Used to It, almost Tom Friedman's book although the subtitle seems to be Friedman's message.
2. The World Is Hot: Cool It - someone needs to write this one.
Update:
3. The World Is Curved: Hidden Dangers to the Global Economy

For the record, I haven't read any of the above.
