The last episode of Season 5... not one by choice, mind you, so much as a mistake on CN's part in regards to the episodes leaking, though their airing schedule isn't particularly great either... but still. It's like how "The Ollie" got leaked; we can't let that affect how we perceive the episode, even if it is a little tempting.
That doesn't mean "The List" is a disappointment by any means; it's probably one of the most straightforward and enjoyable episodes in the backhalf of the show's fifth season.
What makes it such a successful episode is its sheer simplicity, and how that allows for the show to contain, in 11 minutes, a near-all-encompassing array of great gags. Episodes like "The Compilation" exist wholly to do the same general idea, but the narrative tying into the jokes itself is crucial to such an episode's execution, and "The List" was such a creatively-freeing idea that it allowed the show to make whatever jokes it wanted - among them being holistic medicine, the illogic of charity marathons, and a journey across the world online - without ever interrupting the flow of the episode.
