Well I was partly cloudy before I watched it and after I'm leaning towards partly sunny I suppose.
Since my youngest son 10 yrs old will be traveling to Boston in a few months for his Black belt test I can assure you the group of kids punching and dancing are not (Black Belt)ninjas.
My oldest(14) will also be traveling to Boston in a few months for his Black Belt test in weapons.Hes also approx a yr away from his Karate Black belt test.
That said...I'll show them this video in the morning and they'll probably get a "Kick" out of it.
