A few days ago, while browsing internet, I found a video showing an Indonesian policeman of Gorontalo called Briptu Norman Kamaru. He loves singing and dancing like a bollywood artist. On regular working days, he usually sings and acts like a bollywood star does. You'll find how funny he is when you see his video.
But, perhaps he has talent on it, his friend took a video of him singing and dancing in the office, and then uploaded to youtube. On the video, you can see he lipsync the song Chhaiya Chhaiya (song of the film Dil Se) very perfectly, just like a real bollywood singer.
He was then interviewed on TV and caught the attention of the people of Indonesia, also the world through youtube and other video sharing site. Now, he's quite popular though. You can often see him on appear on TV singing those bollywood songs.
Now compare Briptu Norman Kamaru's expression with the original one below.
