A few years back I had a lower GI and woke up during the middle of it! Not awake to where I could talk but to where I knew I was in pain and I knew what the doctors where saying. In the recovery room when I was fully awake I told my nurse my experience and she said that there is no way that it happend. So the doctor came in and I told him exactly what he was saying about how big his daughter looked in her swimsuit and how his wife would be ****** if she ever found out what he was doing behind her back. You should of seen the look on his face and the nurse (I am assuming she is the other person! By the look on her face!) The following year I had to have another one done and this time the same doctor came in and said we will for sure make sure you stay asleep the entire time....and they did!!!
