Bob Saget is not the wholesome patriarch of an Alamo Square painted lady, but he played one on TV. Later he played himself in a documentary about a famously dirty joke, and suddenly Saget's flair for family-unfriendly comedy was out of the closet. His new book, Dirty Daddy: The Chronicles of a Family Man Turned Filthy Comedian, takes stock of that transition, which means Saget understands why he's the Full House cast member whose memoir you'd most want to read. What is the effect on a man's soul of having played a part in the Olsen twins' rise to fame? No one man bears that responsibility fully and alone, of course, but Saget's perspective on it seems the most likely to be hilarious and rife with foul-mouthed depravity. So does his perspective on his own life, which of course has been filled with family-associated grief and pain, sublimated into humor, just as the recipe for good comedy requires. Hang out with him and his book this evening.
