Youtube is really a good source for videos and you will never really know when to encounter something funny on that site. Accidentally,i found something that can surely make you laugh. It's a video of a korean kid imitating the way 2pm sing "Heartbeat" before studying his lessons and decided to make a warm-up before digging his notes(just some assumptions XD).
Watch it people, this kid got a future. XD
