Written by a non-geographer, Craig Robinson's Atlas Schmatlas nonetheless reveals a rather subtle understanding of the discipline. It is bitterly satirical -- a sort of South Park meets National Geographic -- sending up stereotypes in ways both profane and irreverent.
The entries are very uneven -- deliberately so, it seems, but some are spot-on. I particularly enjoyed entries for some of the places I know fairly well, such as Brazil and Nicaragua (neither of which is included among the excerpts on the web site). As with any good satire, it is guaranteed to offend -- even I was offended by some passages -- but the overall result is thought-provoking and, well, funny.
