Hallelujah, it's a book! After proving itself to be the "funniest calendar of the year" (according to Gene Shalit), "irresistible" (USA Weekend), and "habit-forming" (Maxim magazine), the Nuns Having Fun calendar has inspired Nuns Having Fun, a book of endearing nuttiness.

Catholic kitsch doesn't get any funnier. Written by Maureen Kelly and Jeffrey Stone, pitch-perfect co-authors of the nuns calendar and the New York Times bestseller Growing Up Catholic, Nuns Having Fun features hundreds of sisters in full habit, cutting loose and having a hoot. Here are nuns in the surf ("This is even more fun than walking on water"), nuns in bumper cars ("We brake for Jesus"), nuns in a beer hall ("Ale Marys"), and nuns in the museum, huddled in front of a study of nudes ("It's okay to open your eyes. Sister Wendy says it's art"). There are nuns on skates, at bat, at the theater, skeet shooting (nuns with guns!), even hitting the slots (you know it's for a good cause). The 125 images are from the 1950s and '60s, black-and-white and possessing a pure retro charm; the written material is all-new. Drawing on their years as parochial school students, the authors explore the lore and legends surrounding nuns, including Favorite Punishments from Nuns, Nuns Say the Darndest Things, How to Recognize a Nun After Vatican II, a Wimple Watch, and List of People Who Could Have Been Nuns.

As Sister says, "To err is human. To laugh is divine."
