It's pretty clear to me many people here have never either had general anesthesia or talked to anyone who had, you can't really time funny one-liners right before you pass out.
Here's how it works:
They'll put a mask with a rubber tube in your mouth for oxygen, and tell you to relax and count back from 10, so you start counting impatiently(it's boring, and there is nothing else to do), wondering when the surgery is going to start.
Ten.
Nine.
Eight.
Now the anesthesiologist is in front of you, checking on you to see if you're OK. "But I haven't finish counting down yet, when is the surgery going to start?" You ask them.
"It's already over", they explain.
Then you realize you are in a completely different room, the tube is no longer in your mouth, but you feel so weak you can hardly move, and the stitches/staples around your new surgery wound is starting to itch.
It's like a segment of your life was cut out and erased into nothingness.
