Google Hates Me

I'm in the middle of the radio show so I'll make this brief. I can't search on Google. In Firefox, Safari, and directly from the Google site I get the same error message: Google error message

Even when I supply the captcha it refuses to perform the search.

Has anyone seen this before? This is bizarre! It's only happening on my Mac. The PC on the same network works fine. Must be something I'm running on the Mac. (Stickam? Wakoopa?)
