Workplace surprise: Dale Jr. AMPs it up at Nashville office

How would you feel if during a typical day at work, NASCAR's Most Popular Driver Dale Earnhardt Jr. strolled in unannounced and handed you an AMP?

That's exactly what happened on Thursday, Aug. 5, at a Nashville, Tenn., office. To the employees' surprise, Earnhardt Jr. was filming a commercial for AMP Energy Juice in their very own workplace.

Dale Jr., shown above with Alex Stamper of Hendrick Motorsports, handed out bottles of AMP Energy Juice to employees and stopped to sign autographs. A few lucky fans got tickets to the Aug. 21 Sprint Cup race at Bristol Motor Speedway, courtesy of AMP Energy Juice.

Many of the employees started snapping photos and posting them to Twitter, allowing others to share in their workplace surprise. So much for being productive, right?
