Absolutely hilarious. Genuinely all-ages fun. I highly recommend this for parents who have a wide range of ages to please with the nightly read -- or for anyone who enjoys great humor writing. My son and I sat down with it tonight, and the Mohawk-sporting teen was laughing as much as I was. Clever and funny and makes some great points without being ham-handed. Can't wait to see what other Babymouse books my library carries.
