Celebrate St. Patrick’s Day by Giving Back with Guinness

“Extra” is celebrating St. Patrick's Day with a pint of Guinness and a foamy mustache! “Extra's” Mario Lopez and Mark Wright joined in on the fun for a good cause.

This year marks the 200th St. Patrick's Day Guinness will share with America, the latest reminder of the two-century connection between a legendary brewery and its good friends across the Atlantic. The Guinness brand is encouraging all Americans, 21 years and older, to gather with friends, new or old, toast to the many things we all have in common… and give a 'Stache.

It's all part of Guinness' #StacheForCharity campaign, encouraging everyone to post pictures of their self-grown, drawn on, or Guinness-enhanced 'staches as a symbol of unity. For each photo that uses #StacheforCharity and tags @GuinnessUS, the company will donate $1 (up to $100,000) to the Guinness Gives Back Fund, which supports nonprofits that contribute to the common good in our communities.

As always, drink responsibly, and only those 21+ should participate in #StacheForCharity.
