Listen, there's only one excuse for drinking green beer. And that would be if you are with a group of really hot chicks, and they want some.

So, should the luck if the Irish be with you, and you happen to find yourself in that situation, Waterfall Mobile can help you locate the pubs that are serving green brew on St. Patty's Day, via text.

Available in four major cities - San Francisco, Boston, Los Angeles and New York City - text “greenbeer” to MSGME (67463) and select your closest neighborhood. You'll get back a text with a nearby pub or brewery pouring the emerald suds. And hopefully something else for you.
