Not to be outdone at festivals, the Korean boys perform a traditional ribbon hat dance, creating flamboyant circular patterns in the air with the wobble-wobble of their heads. That's the official term, by the way. Wobble-wobble.
Good gracious! Does anyone else's neck hurt after watching this video? Quite dizzying.
I'm going to take some Tylenol now. Tell me when the room stops spinning. Hope you have a wonderful week!
