Michael Phelps now has two DUIs-in addition to the bong-hit-to mar his record. The Olympic swimmer was arrested in Baltimore after going 84 in a 45-mph zone and crossing double highway lines.

The previous DUI was in 2004, and the pot-smoking incident was in 2009. In 2012, Phelps told CNN, "I'll make a million mistakes in my life, but as long as I never make the same mistake again, then I've been able to learn and grow."

Discussion Starters: 

• Did Phelps do the right thing by apologizing on Twitter? What are his other options?
• Does Phelps' apology meet the criteria recommended by The New York Times writer: painful, authentic, probe deep, encourage feedback, and elicit real change in behavior.
