I've worked in our local public hospital in the ICU for over 3 years now and am usually regarded as one of, if not the biggest smart ass in the hospital.
The physicians usually don't say too much (save for the occasional F-Bomb [which I take credit for

]), but here are some of my most recent one-liners that I can think of off the top of my head:
-When getting ready to intubate a Pt. who we knew was going to be quite difficult:
Dr: Does this Pt. have any teeth?
Me: Not for long.
When coding a particularly old and frail Pt who we were certain wasn't going to make it:
Dr: How old is this Pt.?
Me: As old as she's going to get.
Our nephrologist was going in to see a Pt. with salmonella poisoning for the first time:
Dr: Do we have to use any kind of precautions for salmonella poisoning?
Me: Only if you plan on licking her.
When floated down to the ED. I was asked to start an IV on a PITA 17yo girl who was in a MVA. The previous nurse had missed his stick and she was flipping out.
Me: Hi __________, My name is Austin and I'm one of the nurses working down here tonight. I'm going to try to put an IV in you now.
Pt.: I hope you're better than the last guy.
Me: I am
😎
Pt.: You only get one try
Me: Ok....How about I put one in your hand? I see a ton there and I'm positive I can get it.
Pt: You are NOT putting it in my hand!
Me: How about your FA?
Pt. NO!
Me: Ok... How about your A/C?
Pt.: No. I hate you incompetent nurses. Why can't you just put it somewhere where it won't hurt?
Me: Listen, it's a needle. It's going to hurt a little. There's nothing I can do about that. How about you just let me put it where I am sure I can get it the 1st time and we'll be done with it?
Pt.: Listen. It's my arm, and you'll put it where I tell you to!
Me: That's fine, but just remember...I choose the needle size.
I've got a ton more of them from over the years. We are a particularly morbid bunch that work in the ICU. If you can't laugh about some of it, then I feel you should find another line of work. Some days you have to laugh to keep from crying.
