The author's description of Bush Yoga:
"This book has been created to explore the sometimes natural, and sometimes unnatural union between George W. Bush and yoga. It is an experiment. Its meaning at the outset of its creation was unknown, and now that it is complete, its meaning is probably even more uncertain."
