At one point, Sanson throws a fit about being sick and tired of eating "fish, fish, fish, fish, FISH!!!!" before finally settling down into a more deadpan "All in all I have to say I'm a bit tired of the fish."
In episode 12, when Grandis wears her bikini suit, Electra dryly informs the latter that "At your age, you could catch a cold (wearing it)" To which Grandis shrieks "I HAPPEN TO BE IN MY TWENTIES!"
Even funnier, later, when she tries to seduce Captain Nemo, the latter finally says "You may want to wear something warmer. You could catch a cold in that!"
In episode 4, as Jean and Nadia are adrift on the ocean aboard his plane, Nadia begins to make a reflection on how much trouble she has caused Jean, stating "before I die I want to apologize to you." "It's all worth it just to be with you!" Jean replies. Nadia quickly says that she made the apology to King. Jean isn't pleased. He decides to turn the tables on Nadia by declaring that he'll catch "the biggest fish in the entire ocean!" "Jean, you know I don't eat meat or fish!" Nadia protests. "I was talking to King just then," Jean answers. "Isn't that right, boy?" King nods in agreement. A blush forms on Nadia's face as she responds with a melancholy "Oh."
The Grandis gang hug each other and bawl hysterically when they're imprisoned in the Neo Atlantis compound, mainly when the prison soldier tells them that they'll end up decomposed just like their "neighbor" in the next cell. However, after the guard leaves, all three stop crying and loudly declare, "Just kidding!"
Any scene where Grandis and Electra are arguing with each other has some hilarious exchanges.
This exchange in episode 20:
Grandis: At least I have the joy of washing my captain’s clothes! I must be the luckiest woman in the whole world!
Sanson: Ohhhh, bah! And I must be the unluckiest man in the whole world! God blessed me with the skills of a playboy, and just look how they’re going to waste!
Sanson, Hanson: Ohhhhhhhh-ho-ho!
Grandis: YOU NEVER WERE MUCH OF A PLAYBOY ANYWAY, SO JUST SHUT UP AND SCRUUUUUB MY DAINTIES!!!! Just pray that you’ll become a man like my Captain Nemo!
Sanson, Hanson: AAAARRRGH!!!
After Jean (by accident) and Sanson (intentionally) are caught peeping at Nadia and Grandis in one episode, the two drive them off by throwing objects at them in perfect sync with each other. (Nadia is visibly shocked and feels bad about doing so to Jean.)
