sorry, still frothing at the mouth (see ranting below).

Presumably a good thing she didn't watch any other documentaries about bonobo's eh? Once again, hello, monkey/man difference here......we have evolved somehwat not to have the pleasure of draging rotting bags of clotted blood around with us......oh I give up. Instead, heres a nice picture of some bonobos playing 'horse and jockey':
