Do one, see one...

On my surgical rotation, after two months in the outpatient clinic, I just had my first day in the emergency room. When I arrived, my colleague told me, that there'd be a lady waiting for an appendectomy.

Me: "who's going to do it?"
She: "You."
Me: "Who...?"
She: "You! It's your's."
I was laughing my head off. The last one I had seen was when I was in anesthesiology, about 4 years ago, and now I should do one myself. First I wanted to see one, so we arranged that my colleague did it.

Okay, now I know what it is about, I'm eagerly waiting for the next one...
