"The maker of these handcuffs isn't exactly known for their quality craftsmanship. Perhaps you should try the Lezareno model. I'll send you a free sample." This from Regal, who had demonstrated the inferiority of the former model of handcuffs by snapping them right off his wrists.
Just after Sheena joins the party, she makes a comment about how she'd never forget seeing a guy like Richter because he fell for the oldest trick in the book. Sheena then falls into a pitfall and Regal apologizes in a tone that fails to hide how amused he is.
For that matter, ten bazillion of the skits as well. They turned the funnyUp to Eleven for the sequel, it seems.
Full voice acting on the skits (which didn't make it into the English-language release of the original) works wonders.
Sheena and Regal talk about how fond Zelos is of his half-sister Seles is, followed by Tenebrae twisting their words to make it sound like they're insinuating he's in love with her. Zelos is not amused.
Colette summarizing up Raine's Ruin Mode in one skit. Emil is appropriately creeped out.
Tenebrae making a pun so bad that Raine and Genis attack him for it.
Ratatosk Mode Emil and Marta having a fight and in the skits, Marta full on ignores him by talking to everyone else while R.Emil is trying to get her to talk to him.
Not to mention Decus' intro scene. Acts like Emil WANTS him and forces his hideously foul-smelling cologne on him. Cue pop-up box:
Eau de Seduction was forced on you!
Even Marta and Emil's battle victory quotes are pretty funny.
Marta: There's no victory before love! Emil: So you lose if you there's no love? Marta: Yes! So please, tell me you love me! Emil: ...We can lose next time.\\
This one's good too, especially as Ratotosk Mode Emil says his line completely deadpan.
Marta: Beautiful roses have thorns! Emil: Beauty, Marta has a fang. Marta: Be a little more enthusiastic!
During their trip to Palmacosta, post-attack, our heroes come under attack, but are saved by Zelos. Who then flirts with Marta by twirling her, and says this immortal line: "My darling kitten, you're not hurt, are you?". Marta and Emil's expressions... they have to be seen to be believed, and emoticans can't accurately represent their expressions.
Decus' Mystic Arte's intro. He lovingly stares at a picture of Alice...which then randomly gets burned for no reason, putting him into a rage and slice you up for it with the letters L-O-V-E.
When the party discovers that the fires started in Izoold are caused by a light-frog, Tenebrae insists that they call it by it's proper name - Nazdrovie. They just keep calling it light-frog anyway just to spite him, and when he finally caves and starts calling it a light-frog as well, they all switch to calling it a Nazdrovie instead.
When the party escaping from Alice and Decus in the Ice Temple, one of the skits has the party trying to have a conversation mid-chase, only for Tenebrae to cut them off and declare a ban on speaking so they'll focus on running. Cue more skits of Tenebrae trying to speak and everyone yelling at him to be quiet.
In the second fight with Magnar, if you use enough lightning artes on him, his hair will turn into an afro.
After hearing endless flowery incantations from Album Atrum, it's kind of funny to hear him suddenly yell "YOU PIECE OF CRAP!"
In the PS3 port, one of the accessories you can get for Emil is this.◊
Tenebrae's nickname Tenebie is this. Colette gives it to him and sticks to using it because she's Colette. Everyone else in the original cast uses it to troll him.
