Capping off nearly three hours of jokes about Fyre Festival and Twitter, Katy Perry ended her gig hosting the VMAs with a performance of her Witness single "Swish Swish." Drawing on the basketball-themed surreality of the track's video, she performed the track dressed as a basketball on top of a much bigger basketball. Nicki Minaj emerged from inside the ball dressed as a referee to deliver her verse before Perry flew threw the air to dunk a normal-sized basketball. Sports are good! As are the VMAs! Good night!
