An angry Serena Williams was penalized a point for unsportsmanlike conduct when she "walked toward the line judge, screaming, cursing and shaking a ball in the official’s direction, threatening to “shove it down” her throat" according to msnbc.com. That point penalty cost her the game against Kim Clijsters. Oh Serena, it never pays to be a diva.
