March 9, 1967 –
The Star Trek episode The Devil in the Dark aired on this date.

In it, the Enterprise arrives at Janus VI, where Kirk must deal with a mysterious creature that is destroying machinery and menacing the miners. This episode marks the first and only time an episode begins without the Enterprise or its crew being involved in the teaser scenes before the main credits.
This episode was the first time McCoy used the phrase, “I’m a doctor, not a (blank)” when Kirk asks him to help the Horta, finishing the line as, “I’m a doctor, not a brick layer!” An earlier version of this phrase is used in The Corbomite Maneuver, when McCoy says, “What am I, a doctor or a moon-shuttle conductor?“
