I, for one, favor the chicken noodle soup dance. I'm tired of all this snap-hop "lean your shoulder," "lean with it, rock with it," "snap your fingers" crap, where they try to get by on the minimum level of physical exertion and call it dancing. What's next, D4L's hit single "Clench Your Colon?"
The CNS dance, hand gestures aside, is practically the Running Man. If you've been keeping sharp on your Roger Rabbit, it'll take maybe a half hour of adjustments, and there you are!
Youtube needs to keep the white suburban kids in check, though. You look for any dance or hit single, and you get a bunch of "wacky" WASP teens doing bad versions of the steps or lip syncing in front of a webcam. I'm still fuzzy on what the harlem shake is!
