9. The Original Series "Spock's Brain"
Wow. What a crap fest to the Nth degree. I don't know what I can really say about this episode that hasn't been said before. A race of moronic females steals Spock's brain to run their super advanced computer because they're too stupid to do anything for themselves. You know, come to think of it, I'm not entirely sure that it wasn't those same intellectually challenged bimbos who wrote the episode. I can usually find something tolerable about ANY Star Trek episode. This episode, however, that is pretty close to impossible.
