WTF? Barney Teaches Kids to Brush Their Teeth

UPDATE: YouTube removed to original video, so here’s another. Skip to around 1:10 into the video.

I’m not sure what Barney was thinking. Having a kid make rapid thrusting movements with his hand into his own mouth, loving it, dancing around, so excited. in the beginning of the video, why is Barney shaking his gut so damn fast? This video is weird.
