I have previously shown my dancing son. Latest craze is to "shuffle" (he starts shuffling about 15 seconds in the movie):
Oh my, if he just spend as much energy on his homework!
And yes, I also hate his sagging pants.
And yes, I also think the music is horrible.
And yes, he has ADHD, but he neither crawls on walls nor ceilings. He is just a happy boy with concentration problems who likes to move his body.
It is never dull at our house. :)
