Hack wrote this book after he learned that his friend Snow Mercy had founded an organization called The Nipple Immunity Program (NIP) which was started to educate the public that diseases of the heart, lungs, stomach, kidneys, liver, lymph nodes and mammary tissue result from smothering our nipples under clothing. The group’s mission statement claims that “Our nipples need bacteria, viruses, fungi, and fresh air to be healthy.”
Hack supports the aims of NIP mainly because he really likes nipples.
