Laughter is the best medicine and this cute little boy will surely give you reason to laugh! The video below shows a group of kids having fun in their music class. The teacher plays the guitar while all the kid listens and jam with the music. While everyone in the class is busy clapping, one kid cannot stop himself but to laugh every time the song stops. The kid laughs hysterically and even the teacher cannot help herself but to the same. I bet everyone watching the video is also affected by this contagious laughing! There is really nothing like children laughter to bring happiness to the world!
