Bill Maher is NOT buying the moosepoop in Bristol Palin's new book.

This is VERY funny, and most of you will love it.

However for those of you unfamiliar with Bill Maher, or HBO for that matter, I should warn you that this clip contains adult content, so make sure the kids are not anywhere near your computer when you click "play."

Oh, and you probably should make sure your don't have a mouthful of coffee either.
