I remain a sucker for fun and unusual flash mob videos, and here’s one: A group of senior citizens busting some well-choreographed moves to the Black Eyed Peas’ “I Gotta Feeling,” unleashed on the perhaps suspecting crowd at the Arlington County Fair on Friday afternoon.

As always, the news hounds at ARLnow.com broke this story. They report that the mob was corralled by Arlington’s Office of Senior Adult Programs and choreographed by Ms. Senior Virginia 2012, Kathy Fanelli. “We are still hip and happy,” Fanelli says in the video. No doubt.
