Chris Farley’s older brother Tom is director of the Chris Farley Foundation, an institution dedicated to educating young people about addiction and inspired by the tragic early death of his comedian sibling. Farley has teamed up with Colby (coauthor of Belushi: A Biography and also a National Lampoon Radio Hour head writer) for this rip-roaring memory mosaic, talking to “all the people who either knew Chris the best or were there at the important moments in his life.” The interview quotes have been rearranged into a chronological narrative, which starts with Farley’s childhood pranks in Madison, Wis., and moves on to the Marquette University theatricals that revealed Farley’s flair for improv. Chicago’s Second City catapulted him to Saturday Night Live, where he performed many well-remembered characters. Next came movies, but drugs, alcohol and rehab lurked in the background of his rise to fame. Molly Shannon recalled: “He was just indulging in everything: girls, Chinese food, drugs, booze, cold syrup. Everything.” With talents such as Mike Myers, Chris Rock, Conan O’Brien and David Spade analyzing his humor and detailing Farley’s escapades and hijinks, this is a boisterous book the comedian’s fans will want to buy, borrow or steal.
