OAHU (CBS 8) - Some San Diego teens got a presidential surprise along with some frozen treats, when they ran into President Obama in Oahu Thursday.

The president had returned from Washington to rejoin his family on their Hawaiian vacation.

While there, they stepped out for a favorite frozen dessert of shaved ice. Along the way, they stopped to greet bystanders, including some local kids.

They even got a chance to shake the president's hand before the first family returned to their vacation home.
