I got 22/30 answers correct on this very difficult "IQ test," which apparently puts my IQ at about 140.

Quote: "There is no time limit, and reference materials (books, computers, internet, etc.) may be used, but soliciting or receiving help from other people is against the rules."

Taking about an hour to finish, I used the following reference materials: Google (avoiding pages that reference this test), Wikipedia, Thesaurus.com, Dictionary.com, IMDB (for one question), and a Perl script I wrote that allows me to search the dictionary via regular expressions :-)

The questions I got wrong: 4, 12, 15, 18, 20, 22, 26, 30.
