When several people of similar (and high) rank or professional stature are gathered, and greet each other with their titles. For the principals, it is short hand for "Wow, we are all really awesome and successful. Isn't that awesome?" For the audience, it serves to point out that this is a meeting of Big Wigs, who will make Important Decisions and discuss Important Things.

The script would look like this:
->'''Chase:''' Doctor. (''shakes hands'')\\
'''Series/{{House}}:''' Doctor. (''shakes hands'')\\
'''Foreman:''' Doctor. (''shakes hands'')\\
'''Cuddy:''' Doctor. (''shakes hands'')\\
'''Cameron:''' [[OverlyLongGag Doctor.]] (''shakes hands'')

Seen with doctors, high ranking military officers, and [[BlueBlood members of nobility and aristocracy]]. A variant is to have introductions between people with the same name. Can be combined with RockyRollCall. This trope is almost always played for laughs, and happens to be TruthInTelevision.

Not to be confused with the 1989 sitcom ''Series/DoctorDoctor'', [[WesternAnimation/TheSecretShow the leader of T.H.E.M.]], [[StockShticks "Doctor, Doctor" jokes]], or [[NotThatKindOfDoctor people who hold more than one kind of doctorate]].

Alton sometimes plays into it and adds even more when all the "chef"ing gets particularly noticeable.


* In ''Theatre/AnyoneCanWhistle'', [[SeeminglyProfoundFool Hapgood]] explains that this trope is the reason that everyone thinks he's the local asylum's new doctor when he is actually its latest patient.
