I look for the same regard for logic and knowledge and understanding in those I'm close with. I also appreciate people who are willing and able to learn new habits, and discard old habits, based on new information or greater understanding or changing circumstances. If you can appreciate (and perhaps best me at?) my particular brand of alternately dry, obscure, and ridiculous humor, that's just icing on the cake.
Overall, I'm more Fry than Laurie, more Hobbes than Calvin (in all possible senses), more Chapman than Cleese, more Alton than Emeril, more Stiglitz than Smith, and (much) more Obama than (not sure what name to put here, but it probably doesn't really matter). I have a knee that sets off airport metal detectors, I unabashedly dig through trash bins to rescue recyclables, and I'm vaguely disturbed by sentences in the passive voice.
