When I had my first knee surgery they knocked my ass out. There was some issue with the heart monitor thingy as they were starting to inject the good stuff. All I heard was the constant sound that you hear in movies when the mofo flat lines (I have no clue if that actually happens or not in reality).
As I was getting hazy I remember saying "If I wake up dead, I'm going to be pissed...". According to the doctors, my next line to the hot nurse and last thing before I blacked out completely was "...but if I wake up with you giving me mouth to mouth, that would be good". I don't remember that part.
