With the World Cup in full swing, some of adidas’ American athletes are in full-on rally mode.

Dwight Howard, Reggie Bush, Dale Earnhardt Jr. and BJ Upton are all taking part in the stripes’ “Every Team Needs A Fan” promotion.

The guys are trying to lure their fellow Americans to support their team in South Africa with online activities, contests, quizzes and videos on adidas soccer’s Facebook page.

They’re also competing against each other to see who can generate the most US support. If you haven’t seen enough of Dwight Howard acting crazy in front of a camera, check out his videos below.
