Olympic gold medalist Michael Phelps offered a classic celeb apology: Admit behaving badly while really not admitting he smoked marijuana. Blame youth/inexperience/Satan. Promise to reform. Something short of "I didn't inhale." His semipublic embrace of a bong is news if he presents himself as the anti-drug athlete. Otherwise, no, it isn't. However, the aftermath is news: renewed and canceled endorsements, suspension from competitive swimming and Mayberry cops investigating whether to charge him with a crime (they ended up not charging him).
