Archive Panic: 232 theatrical cartoons, an equally large number of made-for-tv cartoons, and decades worth of newspaper comics and comic books. Good luck.
Big Lipped Alligator Moment: In "Morning, Noon and Night Club," Bluto is going around punching out Popeye's face in posters of him and Olive's nightclub routine. He does yet another one after Olive turns down his date offer — and as he walks away, a goat suddenly sticks its head out of the hole and bleats as Bluto tells it off. What a goat was doing behind that wall is never explained, and the goat never appears again in the short.
The short It's the Natural Thing to Do, as well as the later Famous Studios short The Hungry Goat, which feels more like a Tex Avery cartoon with Popeye thrown in as an afterthought.
The short Wotta Nitemare, although the bulk of that short was one big Dream Sequence.
There's also "Popeye meets William Tell", which for no discernable reason decides to throw our hero into medieval europe and have him encounter William Tell. And it only gets stranger from there.
Similar applies to the episode "Popeye Meets Rip Van Winkle".
"Be Kind to Aminals" would have been a standard Popeye outing, if not for the bizarre, one-time recasting of Popeye with his radio voice actor, Floyd Buckley, who sounds like an even older Popeye with a bad head cold.
Breakout Character: Popeye came out of nowhere as a oneshot character for an already long established newspaper comic, and wound up becoming so popular that he not only took over the strip as the main character (sidelining it's original lead, Ham Gravy, who eventually vanished altogether) but became one of the most iconic comic and cartoon characters of all time. At his peak in the 30's, he was even more popular than Mickey Mouse, and he continued to remain that way in several countries.
Breakout Villain: Bluto was a minor oneshot villain in the original Segar comics, but the Fleischer cartoons turned him into the series leading antagonist, and made him as iconic as Popeye and Olive Oyl.
Broken Base: Some hate the 1960s shorts for relying on limited animation and not having the charisma of the Fleischer and Famous shorts, while others like it for being more faithful to the comic strip.
Crazy Awesome: Popeye given the sheer level of insanity some of his feats.
Fridge Horror: If you know a little about the chemistry of spinach. Spinach and its relatives are high in compounds called oxalates, which when ingested repeatedly over a long enough period of time, precipitate calcium from the blood to yield calcium oxalate, the main component of kidney stones. Ouch. Interestingly, the supposed reason for Popeye's super strength was the amount of iron in spinach. The oxalates would still negate this by binding to the iron to form iron(II) oxalate.
"Funny Aneurysm" Moment: In one cartoon Bluto, in a rare moment of Genre Savvy-ness, destroys the world's spinach supply with an powerful herbicide made from DDT. What it's called in the cartoon, Drop Dead Twice, proved to be appropriate name for the real DDT, at least with regards to birds.
Genius Bonus: From one of the later theatrical shorts, "Insect to Injury" (1956), one gag involves the termites eating Popeye's piano, revealing a harp hidden inside it. Music history fans will take note that the harp was in fact a direct precursor to the piano.
Growing the Beard: The theatrical cartoon series got off to a strong start, but the series really crystallized when Jack Mercer took over the role of Popeye from "King of the Mardi Gras" and onward.
For the Segar comics, Popeyes introduction was where Thimble Theatre truly found its footing, and in turn Its run with Popeye reached its creative peak with the critically acclaimed "Plunder Island" story arc.
Memetic Mutation: Everybody knows at least the first verse of Popeyes iconic theme song and it's many parodies, even if they only have passing knowledge of the cartoons. Note that it was a meme well before the internet came about.
Popeye's love of spinach has also become a cliche that's ripe for parody and references.
Rooting for the Empire: Some fans' reaction to the racist episode "Big Chief Ugh-Amugh." The Chief, though expressing his desire for a bride earlier through song, didn't actually say anything to Olive about it or make her stay. Instead, he gave her some gifts. She wanted to stay, and it was Popeye who appeared and started picking fights and insulting people.
Seasonal Rot: By the mid-1940s, the Famous Studios Popeye shorts became increasingly formulaic and stale, and the timing and animation took a hit in quality. By the 50's, the series went through such a clear budget crunch that they were forced to make an excessive amount of clip show episodes or remakes of older shorts. Roughly 17% of all Popeye theatrical cartoons from both Fleischer and Famous Studios were either remakes, semi-remakes or clip shows, that's roughly 38 cartoons in all! However roughly only 3% (4 total) of the Fleischer cartoons qualify, whereas a whopping 28% (roughly 34) qualify for Famous Studios.
So Bad, It's Good: The made for tv Al Brodax Popeye cartoons, which are usually regarded as being embarrassingly cheesy and cheap cartoons, even for the sixties.
Ugly Cute: Popeye in the later cartoons. His earthy appearance and personality never changed too drastically, but he became much more round looking and genial as time went on.
Popeye as an infant, of which we get a glimpse in Goonland.
Values Dissonance: The short "I Yam What I Yam" portrays Native Americans in a very racist light. Popeye and Bluto are also frequently quite sexist in their treatment of Olive Oyl, who usually doesn't seem to mind.
Popeye's also beaten up Mexicans, Japanese, African natives, and the like — he's equal opportunity when it comes to brawling.
This would fit with Elzie Segar's original conception of Popeye as a near-indestructible sailor of immense strength long before spinach entered the plotline.
This seems to be all but confirmed for the Fleischer cartoons, where for example in "Can You. Take It" Popeye survives all of Blutos insane "initiation rituals" even being pressed into an iron maiden! And this is BEFORE he eats the spinach!
Base Breaker: Popeye avoids eating spinach until he's force-fed with it and discovers it makes him super. MAD magazine's parody of the film lasted for just one page, with the cartoon Popeye putting it to a stop for sheer ridiculousness. Though Popeye's association with spinach is more due to the cartoons than the original comic strip where Popeye is super-strong and indestructible on his own.
Narm Charm: Popeye's singing and dancing probably couldn't be pulled off by anyone but Robin Williams without inducing frightening amounts of Narm.
Special Effects Failure: The octopus — the climax was shot late in production, by which time the whole movie had gone well over budget, and Paramount wasn't willing to lay out more money for more convincing practical effects work.
