P.S. No self-respecting neurosurgeon would spend more than 3 seconds thinking about whether or not Nick Riewoldt was concussed. Oh, and no self-respecting neurosurgeon would use the term "concussion" -- it is a lay term, only still used in sports medicine.
Add to that no self respecting neurosurgeon would hang out on the couch with a person who gets his t***ies off by having a username Phil McCreviss.
Phil's crevice is filled in all right but that butt plug should really be in the hole at the top of his head.
