The sequel to I Remember You, Simon and Marcy. The setting is dark, and it doesn't try to hide the grimness of the world they currently live in, but Simon and Younger Marceline's love for each other is so heartwarming, their interaction is so perfect and believable, not to mention the beginning where Jake questions why they invited Ice King. Her answer? 'Because I love him.' Plus, theres something that just strikes me as sweet about Finn and Jake playing basketball with Simon on friendly terms, no animosity.
"New Kidney in Town". It's full of soft, funny and heartwarming moments. Chris with his crotch on fire, Brian willing to die to let Peter live, Stewie blowing snot bubbles crying his eyes out and a heartwarming ending with Chris and Meg. All capped off with Barack Obama singing "Honestly Sincere", this is one of the best post-cancellation shows ever.
The Goof Troop episode, "O, R-V, I N-V U." PJ-centered episodes are always very good, and this one is no exception. However, three things in particular made this one stand out among the others: 1. It was the only episode that actively played with Pete and Max's Not So Different dynamic. That was even the major point of conflict, since it led to a Why Are You Not My Son? situation. 2. It contains one of the most heartwarming moments in the entire series, Goofy giving PJ a heart-to-heart and essentially telling him he's better than he thinks he is. And 3. Aside from the talk, he also got to save the day by excelling at the very thing Pete was heaping praise upon Max for. Talk about a nice meaty bone!
Justice League: "Only a Dream." This has two major reasons why I love it. One - and I don't mean to give the Draco in Leather Pants-ers or Misaimed Fandom any fuel - Dr. Destiny, aka John Dee. This guy is a super-cool, super-loathsome villain. His powers afford a fascinatinglook into the psyches of the superheroes. And that brings me to my second reason, and that's Superman. The series seemed to delight in emphasizing (or maybe even creating) dark aspects of the Man of Steel, and I enjoyed the ability to see him as his old Ideal Hero self, being completely devastated by his worst fear - losing control and having to watch as he unintentionally kills the people he would give his life for.
Rocko's Modern Life: "Wacky Delly". One of the funniest television cartoons ever. It has to be seen to be believed.
One of the most famous episodes of The Simpsons from its Golden Age, Cape Feare. Almost universally agreed as the best Sideshow Bob episode, it's the first time he goes after Bart directly and easily one of the funniest. Additionally, it was one of the first Simpsons episodes to have the entire plot as a movie parody. Finally, it gave us classic gags such as "The Bart, The", "Bart, you wanna see my chainsaw and hockey mask?" and the rake scene.
Another classic episode is "Marge vs. the Monorail." The opening parody of The Flintstones is hilarious and things only get better from there. Lyle Lanley is a perfect villain with a catchy tune to convince the town to buy the monorail, which eventually breaks down and endangers everyone on board. The jokes all work and Leonard Nimoy's cameo is perfect. Since the episode was written by Conan O'Brien, it was bound to be a fan favorite.
