Who Should Be Most Embarrassed?

All right, I think the week merits this conversation: Who should be the most embarrassed by his or her conduct in public this past week?

Was it Serena Williams, whose tirade and threats cost her a tennis match she was about to lose anyway?

Was it Representative Joe Wilson (R, South Carolina), who broke protocol in the congressional chamber by shouting "You lie!" at President Obama during his health care address?

Was it disgraced former governor Rod Blagojevich, who reacted to the apparent suicide of his close friend, codefendant and possible witness for the prosecution, Chris Kelly, by suggesting that prosecutorial pressure on him to "lie" about the governor's actions led to his suicide?

Was it Michael Jordan, who used his induction into the Basketball Hall of Fame as an opportunity to publicly ridicule people with whom he's had decade(s)-long grudges?

Was it Kanye West, who grabbed the microphone from award-winner Taylor Swift to berate the voters for not selecting Beyonce instead?

Was it someone I'm overlooking? Was it me? Was it you? Let's try to learn together from the most uncivil week in recent memory.
