Best Episode Ever S2E6 - Star Trek (Part One)

Thanks to Dave Brodbeck for chiming in on the two-part epic that shall be Best Episode Ever's recollection of Star Trek: The Original Series.

Star Trek Theme
(lyrics for those who didn't believe me)

Beyond the rim of the starlight,
my love is wand'ring in star flight.
I know he'll find
In star clustered reaches
Love, strange love
A starwoman teaches.

I know his journey ends never.
His Star Trek will go on forever.
But tell him while
He wanders his starry sea,
Remember me.
