These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Bizarro Episode: Strangely has nothing to do with the episode titled "Bizarro." One episode may count for being the only non-comedic episode in the series. It was redubbed by the 2021 actors, but using the 2020 script, just to show how boring the old show was.
Yost: For your information, the Dutch Resistance was a crucial factor in the Allied victory in World War II.
Sparks: Oh yeah? Why don't you go tell that to Anne Frank?
Ensemble Darkhorse: Captain Murphy. There's a reason that many people consider the episodes after he was written out of the show to be inferior.
Ear Worm: The theme song is surprisingly lyrical and catchy as all hell.
Fridge Horror: The Other Wiki lists the ranks of the main characters where known. Guess who had the highest command after Murphy/Shanks (and presumably had control of Sealab when they're between captains)? Sparks. (He's a commander, the others are either lieutenant commander or lieutenant.) Granted, he's one of the non-stupid characters. He's just also insane and evil.
Lampshaded when, in one episode, Sharko is seen jumping his motorcycle over a large tank filled with Fonzies.
Positive Discrimination: Frequently played with with Debbie Dupree (only main female character) and Dr. Quinn (only main African-American character); the show will set them up for this trope, then suddenly have them grab the Idiot Ball or show Jerkass tendencies in order to lampshade the trope. Usually happens to minor recurring character Debbie Love as well.
The Scrappy: Sharko is an in-universe example, where he's regularly mocked and ridiculed. It reached its peak when he appeared on the "Anime Talk Show" special, where most of the special was taken up by everyone (but mostly Space Ghost) talking about how much of a disgusting freak of nature he is before he was finally gutted by Early.
