This is so much better than a flash mob.
The 2015 graduating class of Hawaii's Kahuku High and Intermediate School decided to give their friends and family a treat before they walked across the stage, performing a 10-minute mashup of Top 40 hits. A video description said the students learned the number -- which features parts of Miley Cyrus' "Wrecking Ball," Bruno Mars' "Uptown Funk" and Silento's "Watch Me" -- in just two days.
The performance ends with a thumping rendition of the "Kaipahua Kura," the school's own "haka," or war dance, inspired by New Zealand's Maori people.
“We do the haka as a form of respect usually before football or rugby games here in Hawaii,” Lisiate Tovo, one of the seniors, told BuzzFeed News.
Welcome to the world, baby seniors!
