I found this in those comments too - I'll just add it to the pile:
With Friends Like Him wrote: I'm just glad that Obama's Punahou buddy Bobby Titcomb isn't mentioned anymore as Obama's "good friend". If anyone could derail Obama, it would be Titcomb and his sordid past. You can ask anyone of us who ran in those circles back then, circa 1977 - 1983.
Longtime friend Bobby Titcomb hosted an evening BBQ for Obama and his entourage. Titcomb played basketball with Obama at Punahou High School in the late '70s and the two have remained friends ever since. http://www.cbsnews.com/blogs/2008/08/11/politics/fromtheroad/entry4336985.shtml
