I like Tina Fey from SNL but I do not quite understand why she wrote a book, even after reading it. The only thing that I can come up with is someone told her she should write a book and then it started snowballing. Fey does not seem the type to write a book or to even want to write a book, which kind of comes across in the book. The book was entertaining in parts but large parts I found uninteresting and not funny (sometimes in that horrible trying-too-hard-to-be-funny-so-it-totally-isn't way). I think I only genuinely laughed once. But comedians, especially improv comedians, often do not come across well in the book medium.
I am not a fan of 30 Rock so all the things surrounding the show did not interest me, nor did I find funny. I did enjoy the SNL stories and some stories from her own life (although she seemed to be trying too hard with many of them). Overall not a bad read but I am glad I checked it out of the library rather than paying for it.
