Hahahaha, that is awesome.
I too have experienced alien abduction of a patient, luckily the nurses are usually pretty understanding as they too have experienced this phenomena between their assessment and the doctors.
My favorites are 10, 5, 4, 2 and 1. I can't pick just one. Although number 1 is pretty darn good. He did forget to mention Sumdood's brother, Disguy, though.
Another favorite is what I will call 10b -
Patient: " I don't have any medical problems"
Me: "Do you take any medications?"
Patient: "I take X, Y, Z, L, M, N, O, P and A, B and C." (Hands over bag of medications)
Me: "Oh, what do you take X for?"
Patient: "Nothing"
Me: "Ok, what about Y?"
Patient: "Nothing"
Me: "Ok, what about Z?"
Patient: "Nothing"
Me: "Well, your doctor must have given you these medications for a reason, have you been diagnosed with any of the following 20 medical problems I'm about to list?"
Patient: No, I'm healthy. I don't know why my doctor gives me that stuff.
