If you were watching the live feeds Dan seemed to be the one having the most difficulty staying on. As a matter of fact there were two camera's on Dan and only one on Memphis for most of the competition. So when things got really hairy for Dan I was watching and snapping screen caps. Then I see Memphis falling off on the other feed.
When Memphis walked inside to change close he made a hand gesture at the camera - was that his way of saying he was happy with the results much like Dan said 'thats the way you throw a competition,' after the last POV? I'm gonna start a poll to see what everyone that saw it thought.
Hopefully there will be some video captures of both cameras - or a quad cam to compare. If Memphis did throw it I doubt Big Brother will let us in on it with their editing. They will want it to be a battle for the ages.
