The skit that results when you have someone prepare Sorbet in the ice fields. Or noodles in the desert.
Rita: Who the hell decided to pan-fry noodles in the middle of a searing hot desert?!
The skit where Raven suggests alternative uses for the sorcerer ring, such as having it tell him what Judith is thinking, let him see through clothes, or make pretty girls fall in love with him. Rita clocks him for it.
The skit for getting Judith's waitress outfit, Glamorous Maid is easily one of the best, particularly Raven's reaction to Judith wondering if she should show more skin.
Estelle: Like my boobs could fill out that top! *gasps and runs away*
Rita: (to Repede) "Hey, dog, do something about him, would you?"
Repede guards Rita from Raven and barks
Raven: (unimpressed) "Hn. Seems it's time to put my macho energy to the ultimate test: taming the savage beast!!"
Repede growls, Rita/Yuri make 'wut?' face
Raven: (dramatically) "Gaze upon my manly physique, AND BE AWED!!"
Yuri: (deadpan) "Repede's male."
Raven claiming what he wishes the Sorcerer's Ring could do, like let him know what Judith is thinking or seeing through girl's clothes. Rita hits him with magic for this and Raven decides he wishes it could go back in time and make him shut up before he said that.
Yuri translating for Repede to tell Rita not to be picky and use any gels that Repede gives her.
Karol's "suggestions" for the new names of Belius and Phaeroh when they're revived as Undine and Efreet.
Raven has one of these at the end of a fight, triggering one of the most popular quotes from the game:
Estelle: Our weapons are love!
Raven: *in a Mortal-Kombat announcer-ish voice* 'SEXUALITEEEEEEH.'
Yuri and Karol talking about Estelle being a princess. Karol worries that he was rude without meaning to be to Estelle.
Yuri: Your language has been unpardonable. Captain Karol, the sentence for insulting royalty...is decapitation. Been nice knowing you.
Also qualifying: Yuri, Karol, and Judith punching out Raven for handing Estelle over to the Big Bad, saying he now owes his life to Brave Vesperia. And then Rita, who isn't part of Brave Vesperia, gets a shot at him.
The cooking competition. Where the taste of Flynn's cooking horrifies the judges, including the Wonder Chef, who disappears in a puff of smoke. Then Sodia, being Flynn's Fangirl and all, demands to try the food, only for Witcher to shoot that down. Shame it isn't voiced.
From Tales of Vesperia: The First Strike. Yuri overhears some Guild member boasting about how he ditched his client because the client annoyed him. Yuri starts a fight and Flynn tries to stay out of it until he gets punched. Flynn's usual calm demeanour vanishes in an instant as he charges into the fight.
