Elliot: Dr. Cox, I got a patient with osteomyelitis who needs a bone biopsy. Who do you use?
Dr. Cox: You put me in an awkward spot because I'm here and I want to help but speaking to you would acknowledge your existence and you don't exist. So, I'm going to address the stapler. Hi, stapler, the red is killer. By the way, there's a certain Dr. Brownsfield who's just the most wonderful bone guy... What? What's that, stapler? Oh no, she... she's an actual doctor.
Elliot: Neither of you are very funny!
