Fox v. Franken, Really Fox?

After learning about this farce of a court case, the question I have was what was Fox thinking? Did they really think the best way to get rid of a title implied by a COMEDIAN was to take the case to court? And did nobody in Fox's legal department actually look at the case and say "Uhh guys, we have no case at all. We're just going to make things worse." They basically guaranteed the book to be an absolute hit by trying to shut it up in federal court.  And if they had a legitimate claim to slander then that would be one thing, but then to go up to a judge and argue that Franken's use of "fair and balanced" was enough to confuse people into thinking that Fox sponsored the book, a book making fun of them, is another thing altogether. I almost feel bad for Dori Hanswirth, the lawyer that had to argue the case for Fox. She had to make their ridiculous argument and got laughed at by the entire nation. Who thought that their flimsy argument would win them the case when I'm surprised they even took it to court before realizing it would never work.
