I'm a doctor, not a bricklayer.

Behind the line
What it means
Our interpretation.
McCoy's complaint is the series' favourite running gag: a ship's surgeon asked to do something absurd and doing it anyway. The bricklayer version is the best because Kirk's reply, that he is a healer, explains why the joke works. Across the series he swaps in mechanic, engineer, escalator and more, and fans now shorten it to "Damn it, Jim, I'm a doctor, not a...", even though he was never recorded saying "damn it".

In "The Devil in the Dark" (Star Trek, season 1, first aired 9 March 1967), something is killing miners on the pergium-mining colony of Janus VI. Kirk and Spock find the creature, a wounded silicon-based Horta, and Spock mind-melds with it. Kirk hurries McCoy to the cavern, tells him to treat it, and McCoy sees a being that looks made of stone and protests. Kirk answers by reminding him he is a healer. McCoy does the job by trowelling emergency-shelter thermoconcrete into the wound, and later tells Kirk that he has cured it.
