I got the doc and the nurse laughing.
That's a plus.
They were surprised that I knew my blood type.
(O positive)
I'm not surprised you got them to laugh....what did you do now.... : )
I find it odd that doctors/nurses either are surprised or are in disbelief when we tell them our blood types (I'm AB+) (and I even know my daughters': one is A+ the other A-).
