Robert F. Kennedy, Jr.'s voice

Damn, i'm good. The entire time he was just on Letterman, I thought his voice sounded very odd...like early-onset Kate Hepburn, almost. I thought maybe it's some odd New England thing. So I googled him...found out he has spasmodic dysphonia, a disorder that makes speech difficult and causes the voice to sound quavery...in the words of Wikipedia, thank you very much. Oh, those nutty Kennedys...it's always something.
