Almost 50 years to the day that President John F. Kennedy in his inaugural address asked Americans to get involved by doing good, family and friends bade farewell Saturday to R. Sargent Shriver, who helped lead the way.

Former President Bill Clinton referred to Kennedy's famous line, "Ask not what your country can do for you; ask what you can do for your country."

Shriver, Clinton said at a funeral Mass in Potomac, Maryland, gave the perfect example of public service, both at the bright-eyed beginning of the 1960s and the cynical end of the decade and in the early 1970s.

"He showed up every day and found joy in life," Clinton said of Shriver, first director of the Peace Corps, and a force - with his late wife - behind the Special Olympics. Shriver was Kennedy's brother-in-law.
