Funny quotes? Well, in the English version of KH2 Xemnas sounds very suggestive when he says, "Riku, are you SURE you can trust Sora?" Go look for a clip on youtube, listen, and you'll get why it's funny. 8D
Actually, that quote goes the other way around.
"Sora, are you sure you can trust Riku?"
"Riku, are you sure you're not jealous of Sora?"
Think of the storyline, it really makes more sense that way.
