This is why I keep going to rounds

 Whilst discussing the treatment plan for an icteric dog...

Clinician one: "Is the dog ill?"
Clinician two: "Well, she's bright yellow..."
Clinician one: "Millions of people in the world are yellow and they're not necessarily ill."

Looks can be deceiving

From Andrew's description:

Clinician: "Don't look so worried."
Andrew: "...That's just my face."
