Golf -- all the world leaders are doing it.

Visiting President Obama at the White House on Friday, Japanese Prime Minister Shinzo Abe presented the nation's golfer-in-chief with a special gift: a putter made in Japan.

Abe related the story at a evening reception at the Willard Intercontinental Hotel, where he greeted a ballroom of invited American guests. Abe, 58, told the crowd that he told Obama that his own grandfather, also a former Japanese prime minister, had played a round of golf with President Eisenhower in 1960.

Vice President Biden, who was also at the meeting in the Oval Office, then interjected to ask who had won the match.

"It's a national secret," Abe quipped.

It's not clear whether Abe asked to play a round with Obama, who last weekend hit the links in Florida with Tiger Woods.
