I've been under general anaesthetic 3 times in my life...
The first time was at a teaching hospital - I know the patient before me had created a bit of a bloody mess. One of the juniors was struggling to fit the bracket that would keep my cannulated arm from flopping off the table - a senior came over and fixed it, then asked the junior
"Have you changed your gloves?"
"uhhh ...no?"
"CHANGE YOUR GLOVES!"
The last time I went under, I was chatting with the anaesthetist as he was prepping to put me under - seemed like a nice guy, but a bit of a loose cannon. As he put me under, he said something along the lines of
"We'll take care of you - this was the stuff that Michael Jackson was on."
"...wait what?"
