Go get this book:
Giggle a lot.
Try to read it slowly so you can savor the chapters.
Giggle some more.
Finish it and tell all your friends.
I love Tina Fey and Bossypants did not disappoint. Her subtle, sarcastic humor is conveyed through her voice perfectly throughout the book. Just look at the cover again. Subtle, but hilarious. There are also tragic childhood pictures.
