Don't know exactly where she is from or how she was raised, but I thought she was going to have them "sit in a chair" (press your back flush against the wall, bend your knees into a squat and hold the position as if you were sitting in a chair)...not hold an actual chair over their heads...seems excessively dumb and dangerous. Then there is "watching tv" (laying on your stomach and supporting your body weight on the tips of your toes and your elbows, like you look when you're laying on bed watching tv).
In this end, all that yelling and carrying on just makes her look incompetent.
