A video of a pair of dueling, dancing American priests studying in Rome has gone viral. Reverend David Rider of Hyde Park, New York, and Reverend John Gibson of Milwaukee, first shot to Internet fame when they were filmed in April during a fundraiser at the North American College just up the hill from the Vatican. Rider warmed up the crowd with a lively tap-dance routine, only to be pushed aside by Gibson’s fast-footed Irish dance. Soon they were battling it out, trying to impress the crowd. Journalist Joan Lewis recorded the event and later posted it on YouTube.
