Dr. Grumpy: "Hi, I'm trying to get a neck MRI authorized on a lady with a Horner's Syndrome."
Dr. Heller: "Why do you need a neck MRI?"
Dr. Grumpy: "Because the nerves in question go from the brain down the spinal cord, then into the top of the chest, then back up through the neck to the eye. So they can be damaged by problems in the neck, and I need to get a look at the area."
Dr. Heller: "It's ridiculous that the nerve travels so far. It seems unnecessarily complex."
Dr. Grumpy: "Look, I didn't design the system."
