I guess I'll name a few
Stuck in the Wringer: It's a moral mess for the most part but one thing that makes it stand out is that Patrick actually feels genuinely guilty for what he's done and tries to fix the problem he caused, something that's rare but sweet.
Face Freeze!: Robert Ryan Cory's artwork is incredibly well-done and unique, if disturbing.
Atlantis SquarePantis: The opening was quite nice, keeping the quirky charm of the eleven-minute episode's SpongeBob-Patrickj Dynamic and is probably the most joke-dense. It also had the most tolerable musical number.
Waiting: I don't know why but it's really fun to imagine how crazy it was when they were recording it.
SpongeBob's Last Stand: It may have botched it's moral through hijacking Plankton into it and being extremely one-sided in it's worldview, but it's still a really satisfying one. It tells a story all the way through, show's the emotional rollercoaster SpongeBob went through and, at least from a kid's perspective, I feel that the core gets through that it's good to help this earth.
You Don't Know Sponge: The joke where SpongeBob asks what gender he is and Patrick just yells "pass" gets me every time.
The Card: As damaging to the episode as it is I just think that Patrick's self-awareness bit was pretty funny.
It's a SpongeBob Christmas!: It's been overreported that the animation's incredible and I can't help but agree. It's so fluid, so cheery and so squeezable and captures the essence of both the show and the holidays perfectly.
Planet of the Jellyfish: A few quick gags at least help it from being more freaking confusing as heck than it already is.
Pet Sitter Pat: The striking improvement from A Pal for Gary (and really most episodes) in just about every way, from almost perfecting the pace to giving SpongeBob extremely good characterization, just emphasized by it's dark and disturbing but laugh-out-loud jokes at just about every second. I'd love this episode given I didn't feel guilty towards it's subject matter.
