The smudge looked suspicious. The doctor confirmed: "That's the baby's penis!" Joel's reaction? Pure panic. "I pictured having to go camping and fix a car and use a hammer and throw a football and watch professionals throw footballs and figure out whether to be sad or happy about the results of said football throwing." And so begins Joel's quest to confront his effete nature whether he likes it or not (he doesn't), by doing a 24-hour shift with LA firefighters, going hunting, rebuilding a house, enduring three days of basic training with the Marine Corps, and going into the ring with UFC Hall of Famer Randy Couture. Seeking help from a panel of experts, including his manly father-in-law, a racecar driver, Boy Scouts, former NFL star Warren Sapp and some celebrities, he expects to learn that masculinity is not defined by the size of his muscles but by the size of his heart. This is not at all what he learns.
