Green Beer?
Philistine.... why would I ruin a perfectly good beer with food colouring.... but then again I've had my fair share of the beers you guys have down there
Drink an Irish beer on St. Patty's Day: Guinness, Harp, Kilkenny, Smithwicks, Caffrey's, etc.

.... or better yet introduce yourself to some good friends like Bailey's or perhaps Jameson...
But as ZetaPhi708 have fun, but drink smart... so cab it and know your limit.
