Search Engine Keywords

It's always interesting to note the keywords that drive traffic to your site. My new personal favourite drove someone to my site yesterday:
i poked my crazy ex girlfriend on facebook, is it harrasment
A far more interesting question that some of the others that have sent traffic to my site over the months (e.g., when is the wii fit out?, how do I get sky sports on my phone?). I wonder what the stangest question is that would find my blog on the Google frontpage?
