Patrick Jones takes a look at the best viral videos of Summer 2012. They include a bunch of "Call Me Maybe" parodies, including those by Jimmy Fallon, the U.S. swim team, Chatroulette users, and the Miami Dolphins' cheerleaders. Other highlights include the NASA rover video, Australian hurdler Michelle Jenneke, a 71 year old who thwarted a robbery, people freaking out at Kristen Stewart and that Chik-Fil-A jerk.
