Book excerpt: As seen in Netflix's "Cracked Up: The Darrell Hammond Story", this groundbreaking memoir is a raw look inside the troubled life and mind of an American comic genius. By turns poignant and hilarious, Hammond takes readers from the set of Saturday Night Live, where he was the show’s longest-tenured cast member, to the drug-ridden streets of Harlem and into the twisting corridors of his own unflaggingly humorous consciousness. Mingling behind-the-scenes stories from television’s best-loved comedy series with a dark look inside a world-class funnyman, God If You’re Not Up There, I’m F*cked is a book sure to resonate with anyone who shares a talent for performance, a love of comedy, or a desire to know how an artist can climb from the deepest despair to the very top of his profession.
