Every year, Adam Parvanta creates a lip sync video with the campers at Gorham Rec, and this year they went old school.

It boggles the mind to think that some of these kids weren't even born yet, when Miley Cyrus released 'Party in the USA' in 2009 and Adam says they surprised him.

Adam said, "It blew my mind how well they knew it, and the charisma coming out of those little campers is a riot."

How come we never did cool things like this in the summer when we were kids?
