Aang: You know, you're really pretty for a spirit. I don't usually get to meet too many spirits, but the ones I do meet? Nooot very attractive.-3x02: The Painted Lady(The Avatar didn't win himself a lot of fangirls upstairs on that unfortunate night.)
Right, this work has been in progress literally since The Painted Lady aired last fall.
I took one listen to that line and thought, "What?!"
Seriously, Aang. Clumsy yet endearing attempts to sweet-talk a girl are one thing--though I have strong doubts he'd even realized it was Katara yet--but that one was up there with "We crashed! Right into an Earth Kingdom ship!" and "Father's changed his mind, he wants you home."
