I thought about this, and I considered a few. There was the awfulness of "Swap Meat," the heartbreak of "Abandon All Hope," but when it comes down to it, this was an episode that probably shouldn't have happened. There was only one useful bit of information, and that could have been slipped into another episode. And they killed my favorite minor character! Bring him back for season 6! He'll be missed!
