Awesome Moments: "Untitled" features Moltar fighting Space Ghost and keeping up with him as they exchange blows.
Space Ghost gets one in "Warren", when he blasts the titular character. True, Warren was a sentient potted plant, but considering he tried to steal SG's show and was implied to have done terrible things to him, it works.
Birdman manages to get a couple in "Pilot" and "Sequel". In the former, he sics Avenger to maul the crap out of the constantly berating Lokar. And in the latter, he dukes it out with Space Ghost without getting curb stomped.
The fight between Zorak and the laser-visioned crow in "Eat a Peach" (and the fact the crow held up as long as it did) bears mention.
Bizarro Episode: "Brilliant Number One", where 95% of the episode is in black and white with a tinny humming sound in the background, and Space Ghost is inexplicably acting even stranger than usual, all serving to give the episode an almost Lynchian vibe.
Space Ghost: That's barbaric! ...Is there any left? Zorak: Lemme check...Nope. Space Ghost: I'm gonna miss that little guy.
Space Ghost talking about his one man show "Racism Is Bad" from "Live At The Filmore":
Space Ghost: Okay, I like how it starts, but we need an ending for "Racism Is Bad", because some races are bad.
Pretty much all of "Dreams", from Space Ghost's obsession with parroting Triumph the Insult Comic Dog's "banged a dog up the ass" remark, to filling his coffee mug with his own urine and giving it to Moltar to pour on some children, to Moltar actually saying "shit" uncensored, to the entire premise of the episode being to raise money for "retardos" (not "retarded people." "Retardos.") The whole episode comes off as the Ghost Planet staff not caring if they piss off the censors (which makes sense when you realize it's one of the last episodes to air on Adult Swim.)
This hilarious promo has Space Ghost yelling at some executives over having him engage in unpopular and illegal activity (stalking The Pound Puppies). Nowadays, he is no longer in any position to do such a thing, since Cartoon Network's Senior Vice President Mike Lazzo considers him and the show to be an Old Shame.
Space Ghost blowing up France at the end of "Anniversary" has become this after the November 13, 2015 Paris attack by ISIS.
Following C. Martin Croker's passing, the scene in "Flipmode" where Space Ghost thinks Zorak has been killed by a blow to the head can seem a little awkward. Ditto for "Edelweiss", with Zorak seemingly getting obliterated for good and Moltar singing a mournful German song in his memory.
Growing the Beard: The first few episodes sounded incredibly stilted and odd. It isn't until later in the season that the dialogue began to sound more natural, and vastly improved by the second season.
Heartwarming Moments: The Captain and Tennille manage to pacify Space Ghost and Birdman, in the midst of a vicious fight, with a performance of "Muskrat Love". Which brings everyone together to sing in harmony.
"The Justice Hole" has Dave Thomas giving some encouragement to Space Ghost and acting as a conselor, in wake of his Hostile Show Takeover. Of course, this is then subverted when Zorak, Moltar, and Dave ditch Space Ghost.
"Curses" has Space Ghost cursed by one of his foes to devour humanoid beings to survive. The episode begins with him having eaten one guest, and then proceeding to devour Moby and Emo Phillips, onscreen. Despite the Limited Animation, it gets really creepy with his glowing red eyes and menacing demands for Moltar to bring on more guests. He eventually devours both Zorak and Moltar. It turns out to be literal Nightmare Fuel, given it's a dream of Kirk the Storyteller.
Another aspect that makes it especially creepy is Space Ghost's Villain Teleportation in this episode. Moltar attempts to flee at the end, only to get caught by SG manifesting in his control room.
"Snatch" also has a pretty disturbing premise, where replicating pods invade the station and steadily grow. When Space Ghost attempts to flee, a giant, disgusting blob engulfs the entire planet, entrapping them. One opens, revealing a vicious mouth that murders Steven Wright (off-screen). And the episode ends with the replicating pods advancing on the three...
That freakish eye on the monitor that unexpectedly shows up after the commercial break of "Switcheroo" (season 2).
A few episodes later in "Cookout", it appears again (thankfully it's only for a second).
Warren's...behavior towards Space Ghost. It Crosses the Line Twice, considering Warren is a sentient potted plant, but it's still unsettling to hear Warren's wheezing and attempt to assure Space Ghost that "love and fear are often the same thing".
"In Memory of Elizabeth Reed" ends with Space Ghost returning to the set with a sickle stuck through the top of his head after a fight with an HVAC repair guy, and the rest of the episode consists him acting more and more erratically while accompanied by a disturbing Drone of Dread which gives it a rather unnerving feel.
Recycled Script: "Kentucky Nightmare" and "Baffler Meal" are virtually identical in concept: Space Ghost sells out to a fast food company/failing liquor chain (Baffler Meal/Kentucky Nightmare respectively), which injects obnoxious advertising into the show, and Willie Nelson is the guest. However, it's justified in that "Kentucky Nightmare" was intended to replace "Baffler Meal", which had been shelved (but got made several years later anyway).
Very noticeable during "Baffler Meal", where Willie Nelson only gets 4 or 5 lines, all recycled from "Kentucky Nightmare".
"Seinfeld" Is Unfunny: This show was unlike anything else on the air in 1994 and only got more "out there" as the series progressed. Now almost the entire Adult Swim lineup has taken some cues from Space Ghost Coast to Coast and it's more difficult to see what made it so special.
"Batmantis" features a parody of the Batman theme. Not surprisingly, it's a stock music piece called "Gotham City Hero".
"Urges" features a parody of the theme to That Girl. Again, it's a stock music piece called "Which Girl?".
The episode "Lawsuit" opens with a musical parody of the opening theme to My Favorite Martian. It's a stock music piece called "The Goofy Alien".
"Sweet for Brak" briefly features a sound-alike to the I Dream of Jeannie theme. It's called "Genie in a Bottle".
Tear Jerker: "Sharrock" (titled after and dedicated to Sonny Sharrock, who composed the opening, closing and some incidental music). The song that sounds near the ending of the episode (the "Ghost Planet Anthem") was recorded on one of his final jam sessions before passing away.
Birdman. When he tries to run the show, on two occasions, he's portrayed as a very broken man who receives No Sympathy from anyone and breaks down from the pressure of failing.
Brak's heartbroken reaction to seeing Space Ghost jealously react to his spin-off's success by deriding him and declaring him a talentless hack to Jack Black in Sweet for Brak.
On September 18th 2016, C. Martin Croker (Zorak & Moltar) passed away. That was sad enough, but then Adult Swim posted this image◊. Poor Space Ghost...
"Weird Al" Effect: Most cartoon fans these days would be more familiar with this incarnation of Space Ghost than the classic cartoon version. In fact, some might think Space Ghost only exists as a talk show host and a superhero parody! It didn't help that these incarnations were the ones featured in Cartoon Network advertisements in the 90's and early 00's.
Birdman is a complete and utter wreck (having his wife divorce him, has gone to therapy, gambled, and is very desperate to make a comeback). Seriously, he's a guy you just wanna give a hug to (especially if you can relate to him).
Jan and Jace. Having been abused by Space Ghost in the past, and never being paid for the reruns, they attempt to sue him but ultimately fail when their lawyer Dr. Nightmare (attorney at law) backs out. Even Zorak and Moltar felt bad for them.
