Bests & Worsts Reviews from Amazon

I would like to have known about the offensive (to me) language in this book prior to downloading onto my Kindle. I am willing to overlook an instance or two of the F-word, but I strenuously object to finding it in every conversation in the book. I do agree that parts of the book were very funny, but I couldn't enjoy the humor due to the offensive language. Maybe it's time to give books ratings like movies. At least that way I'd know what to avoid.
