The Way to Eden

The space hippie protest "Herbert, Herbert, Herbert!" is a gag, referring to both Star Trek four-time director Herb Wallerstein, and long-time Executive in Charge of Production Herbert F. Solow. (Spock tells Kirk that the reference to Herbert is "somewhat uncomplimentary" and that "Herbert was a minor official, notorious for his rigid and limited patterns of thought.")

Two times, a shot of Kirk is reversed (presumably to make him face the right side of the screen) The first time he is facing Sulu in a corridor of the Enterprise, the second he is looking where Dr. Sevrin had just run on the planet Eden. Note the appearance of the Star Fleet emblem on the right side of his shirt, rather than the usual left side.
