Is Everyone Hanging Out Without Me? (And Other Concerns) by Mindy Kaling
I have never watched an episode of The Office (should I start watching?), but I picked up this book at the library. It was very funny.
I was at home sick this week and read this book as I rested and recovered on the couch one day. It is a great book to read if you're not feeling that good (physically or emotionally) because it will get you to laugh.
