Bossypants
I was listening to this book while I was exercising, and I have never exercised so faithfully or enthusiastically -- ever. Whether stories about growing up, fitting in (and not) at school, family and married life, the workplace, whatever, the delivery is impeccably timed and wholly enjoyable.
The voice modulation adds another layer of humour too; you'll want to listen closely, as sometimes the funniest parts are the quiestest parts.
I wish I'd made myself take some time with this one, but I can always re-listen: it's that funny.
