So, Serena Williams was one set down and badly losing the second to Kim Clijsters in the US Open semi-final, she was 15-30 down and on a second serve, when it all went wrong!
The line judge called a foot fault and that was that, Serena turned and said "If I could, I would take this ball and shove it down your throat and kill you" - now the real quote has lots of F words in between as well.
If you want to see the full effect there is a YouTube video, posted within minutes apparently.
Anyhow, the umpire, the referee and the WTA tour supervisor reviewed the evidence before them and told Serena Williams that this violation for unsportsmanlike behaviour meant the end of the Championship.
Rightly so, in some sports its hard for the referee as everything is only available in real time like football, but tennis and cricket have more than one referee in addition to modern techniques.
I'm afraid Serena Williams came out of this nothing more than a bad loser, not a great player having a bad day - Serena I hope you get fined big for this and I hope it proves to you that being a cry baby isn't the best way to handle losing.
UPDATE - Thanks to Jeff for pointing out my obvious error, now amended. I blame the time of the day and the fact I was blogging from my Blackberry.
WE ARE ALL IN IT TOGETHER - So I expect you all dined like this last night...
