OK, I included this to make people happy and to add a bit of cheesecake to the mix. You don’t have to watch it, but you will because these people are so happy in their dancing that you cannot help but laugh.
But this laugh will not be your usual grunt (I hate when you do that!). It will be a slow warm smile that vocalizes in a pleasant want.
There are dozens and dozens of “shuffle” videos. I tried to make one, but it would have made you sad.
