Iraqi Jumping Jacks

One of my friends told me that I had to search YouTube for "Iraqi Jumping Jacks" and that it was the funniest thing ever. I'll have to agree. This is some funny stuff. The guy on the far right look like he's having a seizure or something lol, and the guy in the middle is just dancing. I never realized that jumping jacks aren't an exercise that is done everywhere in the world. I guess they take more practice than I thought. In the US you start doing them in elementary school and the military does them all the time. Is the US the only country that does jumping jacks?
