The NoKy Brothers HAHAHA Song is part of Samsung's campaign for spreading encouragement - to share laughs & smiles - during these hard times. It is not a commercial, but a public message campaign. The message that was to be brought is "When going gets tough, tough gets going! so cheer up!" Also, all five members have done a video for the campaign, which can be viewed below: http://www.youtube.com/watch?v=kb3T...gn_Video_t115568.html&feature=player_embedded Link for their campaign: http://www.hahaha4u.co.kr/ Credits: mickytoho@youtube + kiwiprints@asianfanatics
