U.S. President Barack Obama and first lady Michelle Obama drink Guinness in Ollie Hayes Pub in Obama's ancestral home in Moneygall May 23, 2011. Obama sipped a pint of stout and cuddled babies on Monday as a tiny Irish village on Monday welcomed home "a long lost cousin" with an outpouring of affection. Hoisting a glass of Guinness at Ollie Hayes pub as fiddle music played, Obama thus began a four-nation tour of Europe with a celebration of his ancestral roots.
