Funny / The Suffering

The whole scene on the beach with the Mainliner, Slayer, and Fester. You can almost audibly hear the Slayer thinking "Oh crap..." right before it gets killed by a Fester. A few seconds before then, you can even see it poking the body of the Mainliner it just killed, almost like it's making sure it's actually dead.
