This is funny, an expat American has written a Japanese book on Bush-isms that purports to be a useful way to learn English. Excerpt:

"I’m Terri MacMillan. If I'm not mistaken, I may be the first middle-aged black woman, who's a native New York expat entrepreneur living in Tokyo to write a book of commentary on GW Bush's quotes on a variety of subjects, from an everyday American person's perspective.

Bush in Wonderland” includes a lot of background to help people who did not grow up in America see with a pair of American eyes. It also includes explanations of what is wrong, and better ways to say whatever Bush meant to say in each quote, so it's a good way to learn modern everyday American English that goes beyond “this is a pen”. And, the commentary gives you some of the background behind each quote, so that you can easily understand the context."
