Doc, my shoulder is killing me. I can’t sleep, I can’t work; you’ve got to help me.
I saw you in the office two weeks ago for this, right?
Yeah, that’s right.
Did you get the x-ray I asked you to get?
Did you try the heating pad we talked about?
How about the over-the-counter pain relievers I mentioned.
How can I help you.
I think I need a MRI.
[Another deep breath]
They won’t let you get an MRI without an x-ray [see Third Law]
But why isn’t it better?
[Pause for several deep breaths]
