Watch A Classroom Full Of Kids Lose It While B.J. Novak Reads ‘A Book With No Pictures’

Actor, producer, and author B.J. Novak is a multi-talented man, and his latest feat is writing a children’s book that somehow manages to appeal to small children despite its complete lack of pictures. How? Well, because the book ask the reader/parent to say a lot of silly things. “Everything the book says, the person reading the book has to say. No matter what.”

It’s kind of genius, and having a reader who is game certainly helps, but even still, there’s not a child (or adult) alive who can resist laughing at the phrase, “Boo Boo Butt!” He just made me a customer for the second time in a year (I also bought his book of short stories).
