What would be the worst thing to hear with anesthesia???

What would be the worst thing to hear as you are going under anesthesia before heart surgery?

you can't hear nothing under anesthesia, or do you mean before anesthesia?

I assume he means as it's being administered, while counting backwards from 100.

I guess it would be the doctor saying "What? He has no medical insurance?"

You can easily survive, in case we enter the coronovirus

Something like "his pulse is slowing down" would be awful

"Right, he's under. You can start the surgery, doctor".

or, potentially worse

"That's a nice cock. I can't wait to add that to my collection".
