Season 1 of Sealab 2021 was frickin' hilarious. It's weird how bad it got after that season.
I was about to refute you and say that Seasons 2, 3 and 4 were pretty good but after looking at an episode list I realized that all the episodes I remembered fondly were from Season 1. I guess the subsequent ones had their moment though with the show really going downhill after the death of the guy who voiced Captain Murphy.
Season 1 produced one of my favorite exchanges in TV history:
Marco: Well, Debbie thinks this is all about her biological clock.
Stormy: She stopped screaming enough to tell you that?
Marco: No no no no, the other Debbie. Debbie the teacher.
Stormy: Oh, you mean... black Debbie.
Sparks: Woah woah woah, why is she... black Debbie?
Stormy: Not in a bad way, it's just to tell them apart because she's... black.
Sparks: Well, why don't you call her Debbie, and call the other one... white Debbie.
Stormy: White Debbie? That's stupid! I know she's white.
Marco: Then why do you call the other Debbie "black Debbie?" You know she's black!
Stormy: Hey, first off, I really don't think we should be talking about this in front of Dr. Quinn.
Quinn: Listen man, you're missing the point. What if everybody went around calling you "white Stormy?"
Stormy: You mean there's a black Stormy?
Quinn: ... No.
