It seems House played an episode last night that featured fetal surgery. This has started a bit of a debate on Pro-life blogs whether or not a fetus would reach up and grab a surgeon who entered into her mother's uterus during surgery.
It doesn't take much reflection to understand that a fetus under anesthesia during surgery would not have the ability to "reach and grab" the hand of the surgeon. To be conclusive here is a video of fetal surgery on TLC a few years ago. It seems clear that the child is anesthetized and unable to reach and and grasp the surgeon, even though they did pose a "hand in the surgeon's glove" picture.
