On Thursday, March 12, 2009 late-night talk show veteran Carson Daly toasted St. Patricks Day and hosted a pub visit with Guinness Master Brewer Fergal Murray as the duo rallied support for Proposition 3-17, a national movement to make St. Patricks Day an official holiday in the U.S. Adults can join the effort by signing the online petition at proposition317.com or by texting the word SIGN to 65579. The movement this year has an even greater significance, as 2009 marks the Guinness brands 250th anniversary.
