Agreed. I still don't get why every other mention of Jin I see mentions her big boobs. Honestly, it's not like she wore a tube top or something . . . they didn't strike me as being that big.

Mai was Zuko's choice when he was fooling himself that he was a good little Fire Nation prince. In that situation, he was limited to someone a)female, b)of the Fire Nation and c)Not related to him. Unless a new character were brought in (which would probably be handled even worse), his only other option is Ty Lee, and she's just too perky for Zuko. At that time and with the mindset he had, I can accept that he went with Mai.
