It still frightens me a little bit to think that so much of my life was totally devoted to Star Trek and almost nothing else.

This is a call to action—not an action that will make things better in six months’ time or a year’s time, but action that might save someone’s life and someone’s future this afternoon, tonight, tomorrow morning.

Comedy today is not what it was years ago. It's always changing, in particular to female comics. No longer are certain subjects considered to be a male preserve. Women can talk about sexuality and their bodily functions and it can be very, very entertaining. It's changed the impact of comedy acting.
