Unsportsmanlike Behavior

Top women's tennis player Serena Williams talks to U.S. Open head referee Brian Earley after being penalized in her match against Belgium's Kim Clijsters during the women's semifinal match at the USTA Billie Jean King National Tennis Center Sept. 12, 2009, in New York. The title-holder was 6-4, 6-5 and 15-30 down when a foot-fault penalty was called against her, setting up match point for Clijsters. Williams turned to the lineswoman, shouting profanities and pointing her racquet toward her. Later, microphones picked up Williams saying: "I didn't say I would kill you. Are you serious?" Williams was docked a point after her outburst, ending the match. (TIMOTHY A. CLARY/AFP/Getty Images)
