* On our phones. What Alexander Graham Bell meant to say, before he was cut off, was "Watson, come quickly, I need you so to help me out here so that some day people can read romance novels on the subway without anyone around them knowing." Or something like that.

Helmsman Mitchell thinks nothing of calling Dr. Dehner frigid, then trying to put the moves on her right there in sickbay after softening up her defenses with a little verse; for her part, she seems not to feel that either action is particularly inappropriate.
Fortunately, by the twenty-fourth century the situation has improved at least a bit, though the uniform worn by Counselor Troi on the NCC-1701D does make one wonder if there isn't still some distance to go.
