This show hit its peak early on and never again quite hit the heights it reached in this episode (though the troll episode was close). "Dethwater" is pretty coherent plot-wise, which some of the other episodes really can't claim. There are also just a ton of hilarious lines, plus Toki's "underwater friends" scene. And the music is really good (though it is consistently good throughout the series)! I did have to take off a point for the totally unnecessary gross-out gag involving Murderface. Gross isn't funny in itself, and the scene offered nothing more. But even with that, I can watch this episode again and again, and in fact have done.
