Some might see this as disrespectful to tradition, but I think it's just harmless fun. I wouldn't want this to replace the traditional CNY lion dance (or is it a tiger dance?) of course, but they've done the traditional thing and are just adding something different and entertaining at the end.
And I understand if some of you never want to hear Party Rock Anthem every again. But it's worth watching if only for the bit at 1 min 43 seconds.
This seems to have been shot in Malaysia by the way, I think in Bukit Bintang although I could well be wrong.
