Serena Williams is completely devoid of a shred of decency and class. In the midst of losing her match on Saturday at the U.S. Open, she disagreed with a controversial call by one of the officials.

This was Williams' action toward the umpire who made the controversial call:

But Serena angrily confronted the lineswoman who made the call, dropping the f-word liberally and, getting in her face and waving her racket and later the ball menacingly, saying, "I swear to God I'm [expletive] going to take this [expletive] ball and shove it down your [expletive] throat, you hear that? I swear to God."
