Pretty much anything sarcastic Balthier said...I like sarcasm, so I'm always laughing at his quotes.

I remember one that was something like:

'Oh, and here I thought it was going to be difficult!' in regards to the Tomb of Raithwall...but I don't remember exactly. It made me laugh.

Oh, and Vaan being Basch. 'I'm Captain Basch!!' I was laughing so much I could hardly do that part of the game. Silly Vaan XD
