Ok, maybe I'm stating the obvious, but did anybody notice that the way to get a really high score is to drag the hand all the way to the right, move your mouse outside of the flash movie and bring it back in on the left side. This causes the flash movie to think your pointer instantly jumped from the right-most point to the left-most point. Hence the ultra-fast "spank".

Didn't want ya all spending all night spanking the monkey.
