Hayes (sic) Office? The MPAA Production Code, aka the Hays Code, governed the content of American motion pictures before the ratings system was introduced in 1969 (although Code restrictions began to loosen in the mid-1950s). It had absolutely nothing to do with television.
Yes, Star Trek did occasionally manage to slip one past the NBC Broadcast Standards people, aka censors. Like Sulu’s line in “The Naked Time”: “I’ll protect you, fair maiden.” To which Uhura responds, “Sorry, neither!”
A house divided against itself cannot stand.
As a random note…I always get this episode (Dagger of the Mind) mixed up with Whom Gods Destroy, as both deal with psychiatrists (and the psych division jumpsuit is identical in both - yay, continuity), and Whom Gods Destroy reuses the chair prop, which is presented as a different device. Reading the Memory-Alpha page on Whom Gods Destroy - apparently Nimoy was annoyed enough about the similarities in the episodes to write the network. Hah! (I think Whom Gods Destroy is the better of the two episodes, though, so if one had to be tossed from continuity, I’d say the earlier episode should go.)
And the latter episode has Yvonne Craig!
And she herself wore one that said, “I am not Mrs. James Garner”. Their on-screen chemistry was tremendous; it was not hard at all to believe that they were in love in real life.
