You can forgive me for having my head somewhere else lately, but I have to ask: Who is Sarah Palin? 

And: is she single?

I thought I had the number of every Sarah west of the Mississippi, but I was wrong. One of my crew guys J.T. had this issue of Newsweek, and he had the centerfold pulled out. I said, "Newsweek has centerfolds?" He told me that this one did. I wanted a peek, but homeboy wouldn't share. I went to every Borders in Hollywood, and all I found was Obama and Biden ... Boring.

So, will someone in the know, and who knows numbers, let me know if she's single?
