Ok, we got a ton of email on this one.

  The newbies or those who have never choked or hanged to the point of passing out were concerned for the violent nature of poor Misty being throttled in this way.

   The more experienced Gaspers recognized immediately what was happening as it has happened to some of them before.

   When someone is strangled, the reflex action is for their hands to go to the neck and the rope.
Here you notice Mistys hands are not going for her neck, but behind her head.

   When the cloth was wrapped around her neck we didn't realize that a hunk of hair got caught in it.
When the cloth was pulled tight, so was her hair. OUCH!!

   Misty loves to be strangled in this position. She likes to lay there and feel the cloth slowly tightened around her neck.
  She usually passes out quickly but this time she was trying to talk and say something in order to keep from being scalped.
  She continued to try to get her hair undone until she finally did pass out.
Since she was tense this time she continued to bounce and jerk around for a while.

We watch this clip now and then and laugh. Well, I laugh.
She just punches me in the arm each time and says "You jerk".

Now we have arranged a hand signal for
"Let go of my God Damn HAIR !!!"

So for all those folks that were so concerned,
That's why she was struggling so much.
