You Cannot Be Serious

John McEnroe's memoir, written with James Kaplan, traces his rise in professional tennis and the on-court behavior that made him a figure of controversy. He takes readers behind the scenes of life on the tour and speaks candidly about his personal struggles. The account covers his marriages to the actress Tatum O'Neal and the singer Patty Smyth, and his later roles as a father, a player still on court and a television commentator. The title comes from his famous outburst during a first-round match against Tom Gullikson at Wimbledon in 1981. Published in Britain as Serious, it reached number one on the New York Times best-seller list.

Yaro Starak, founder of Entrepreneurs-Journey.com and a self-described huge tennis fan, listed McEnroe among the players whose biographies he reads for their behind-the-scenes stories.
