So let's talk a little bit about behind shaking, now, which is a big, big part of Senegalese Sabar especially with the women. Women of all shapes and sizes dance Sabar, doesn't matter how much you got going on back there, they will find a way to move it and they'll look good. So one of the moves we demonstrated in Series 2 and 3, was the Shimmy, and that's just this one, just to kind of get you to remember what we did before. Just a Shimmy and the Hip Thrust at the end. You remember, one, two, three, four, one, two, three, and four. So that's one way, we do it sideways you can kind of see the side to side movement. There's one other one that we can do, this is our side to side movement, that I demonstrated before, was just a Shimmy while you're picking your leg up. One, two, three, one, two, three, four, one, two, three, one, two. So you're kind of picking your foot up and just kind of shaking, shaking your hips a little bit, just like this, keep them loose. One, two, three, and one, and two, one, two, three, one, and two, one, two, three. This Shimmy's a little bit faster than the one we just did. One, and two, one, two, three, one, two, one, two, three, side to side, and just a little Shimmy. There's one more, well there are a lot of different kind of Shimmies, but there's one more that's very specific, and it's a specific dance, called the Ventilateur, which in French means Electric Fan. So if you can imagine, electric fan, turning around and around like this, that is exactly what the women do during this Ventilateur dance with their Behinds. The Ventilateur definitely a dance best observed in its natural state, when the women are so moved by the drum rhythms that it just comes out. We're not going to demonstrate that here in our beginning series, that's more an advanced move, something that you kind of got to build up the courage to do. But just to get a thinking about it in your head, that circling motion you got to kind of figure out how to separate one side from the other. It's going to be turning around and around like an electric fan. That happens a lot over there in Senegal. If you ever get the chance to go over there and see it, definitely something very interesting to watch.
