Captain Kirk, Leonard McCoy, Spock and Chekov get ready to dive into the pits of someones septic tank. Ewww. Anyway, you'd think they could just phaser everything into oblivion. Maybe they transport their waste to some distant planet, where it grows into a sentient sludge slash tar creature. It then later envelopes Ryker, and kills Tasha Yar. Again. Ewww! What a way to go. Plugging your nose.
