A prisoner of war passing through the camp proves to be a skilled surgeon, and Hawkeye and B.J. scheme to keep him around. Unfortunately, Frank and Margaret seem to recognize him...
Attention all personnel! Dr. Cho has arrived unannounced with the following tropes!
- Aliens in Cardiff: Dr. Paik/Dr. Cho is the second of two Communist surgeons to appear in the series, after Dr. Lin Tan in "Rainbow Bridge". Both studied in Illinois, Paik at the University of Chicago and Tan at the University of Illinois.
- Every Man Has His Price: Radar helps Hawkeye and B.J. fake a profile and dog tags for "Dr. Cho" in exchange for assisting with the nurses' annual physicals. Sparky helps out on the I-Corps end in exchange for the doctor's Chinese Army-issue watch, "straight from the wrist of an enemy officer".
- Hypocrite: Frank regarding Donald:Frank:He could be married, you know, and didn't tell you.Margaret: Remember how our relationship started?Frank: Right.
- Failed a Spot Check: Dr. Paik was uncovered because he could tell the "medics" asking for supplies were actually North Korean. Only one way he'd know that...
- Jerkass Has a Point: Frank and (especially) Margaret ultimately foil Hawkeye and B.J.'s plan, leading to his re-arrest.Potter: It was Houlihan and Burns who put the bee on him. If they can figure it out, anybody can.
- Not What It Looks Like: Dr. Paik tries to help a choking patient when no nurse is around to help; they walk in as he has his hands on the man's throat.
- Majored in Western Hypocrisy: Dr. Paik attended the University of Chicago for his medical training.
- Paper-Thin Disguise: All they visibly to turn Dr. Paik into Dr. Cho is give him a shave and a new uniform.
- Stereotype Reaction Gag: Dr. Paik, despite being Chinese, was trained in Illinois, leading to this:Hawkeye: Maybe afterwards, you'll come to the States sometime and we'll all get together and have a few beers.Paik: Or perhaps you'll take an exotic cruise to my country and we'll share some rice wine.Radar: I bet you know some terrific places for Chinese food.Paik: One or two...but they're in Chicago.
