While the Northern Hemisphere is still celebrating St. Patricks Day, Australians are nursing their Guinness headaches. But before we got stock into the dark stuff we enjoyed an Irish flashmob, courtesy of the cast of the stage musical Riverdance.

The Riverdancers were joined by local high school students at Sydney’s Central train station. Some 100 dancers performed the Irish jig and spread some St. Patricks Day cheer to stunned morning commuters.

I don’t know about you, but I think this is the right way to start every St. Patricks Day. It probably wouldn’t have the same novelty factor in 2012, but right now I’m impressed!
