PBS is running a special on the Kennedys.
One of the scenes showed RFK campaigning at the Fulton Fish Market for his NY Senate run. Someone asked RFK what he thought of the market and he said something like "there's a lot of fish". Everyone laughed. This had come from a Kennedy after all, therefore it must represent wit.
IMO if George W. Bush had said the same, the press would have jeered. "See what I mean? What did the stupid SOB expect, anyway?"
