"I didn't say I would kill you! Are you serious?"

Wow, Serena. Take a chill pill.
An epic screaming match ensued when the lineswoman caught Serena's foot stepping over the baseline while service was in progress during her US Open semifinal against Kim Clijsters last night. After a lot of racket-wielding and cursing, a point was deducted for her outburst, and Serena lost 6-4, 7-5. Earlier in the match, she received a warning for code violation when she smashed/broke her racket after losing the first set.
I'm glad I missed this match, although watching Serena go after that terrified lineswoman is slightly amusing. Apparently, she threatened to shove her tennis racket down the woman's throat. FYI Serena, that doesn't work.
