As if this song wasn't infectious enough, it's now got a music video starring the world's most universally beloved film star, Tom Hanks. It's also features a cameo from Justin Bieber, if you're into that sort of thing.
That video was way more fun than it ever deserved to be. There's even a clever little joke in the onscreen texts, with the emojis spelling out "Run, Forrest, Run." You spot that?
