Wisdom teeth extraction: I woke up, and had tears streaming down my face, not from pain, but from the anasthesia.
Colonoscopy; i remember waking up, and being on my side, and kind of yelling something at the nurse, but I don't remember what, but along the lines of hey, hey, come here. I apologized and was quite embarassed but since I'm sure the recovery nurses have heard it all, she said no problem.
