Is there anything more contagious than the sound of a little kid laughing? No, didn't think so. There's something so innocent and joyful in those high-pitched guffaws that you can't help but chuckle along, even though you have NO idea what's so funny.
So it's no big surprise that the video of little boy has charmed the Internet today. The scene: a music class in New York and the teacher is leading the class in a clapping song. When she has the kids stop clapping, the little boy chortles. When she wants them to go faster, he's hysterical. When she goes slower, he's still laughing. Maybe it's just the strum of the guitar that's go him so tickled!
See if you can figure it out for yourself!
