Sean: You know, I had the same problem when I started working with the dolphins.
J.D.: Okay, that's it. I-I'm sorry, Sean, I'm a doctor, okay? I-I'm teaching humans, not dolphins, okay? So it isn't really helpful for me to know what works on fish.
Sean: They're mammals, actually.
J.D.: Oh, well, Sean! Unfortunately for me, my interns aren't mammals!
Sean: J.D., they are.
J.D.: Ssh. I don't care, Sean!
