Kalvin and Sage's music video

Kalvin and Sage's uncle Nik came over yesterday and made a video of them with their cousin Robyn. They had so much fun and Nik is so fun with them. He directed them and they had no clue why he was asking them to do all these random things, but look how awesome it turned out. They think they are the coolest things in the world because they are now on Youtube....Kalvin's lifelong dream come true.... Now what?
