This Slate piece contains a long list of graffiti transcriptions found on Bagdad walls. The transcriptions are an interesting mix, containing a number of anti-American slogans but also a suprising number of pro-American ones. My favorite one is:

SADDAM HATED TEACHERS AND SCIENCE
AND BOOKS AND SCHOOL BECAUSE HE WAS
ILLITERATE AND IGNORANT AND DID NOT
HAVE KNOWLEDGE OR A CERTIFICATE

I gotta get me one of them certificates.
