Elliot: I don't get it. I've run every single test. I cannot figure out why this guy is in so much pain.
Dr. Cox: Did you run a d-u-h test?
Elliot: What's a D.U.H.?
Dr. Cox: Uh, duh! The guy is a drug addict trying to score painkillers.
Elliot: But he refused drugs.
Dr. Cox: My bad. He is a very clever drug addict. Look, I hate to question your three years of wisdom, but your pain guy is just like a million other drug addicts who walk into hospitals every year with their aches and their pains and their spasms and their cramps and their myalgia and their neuralgia, and their otalgia or any other algia they can possibly think of just so they can get a fix.
