Avatar: The Last Airbender

I'm watching Avatar: The Last Airbender, an animated series from Nickelodeon. M. Night Shyamalan just made a really, really bad movie out of it, which you should only see if you haven't seen the series. Then you can watch the series and both appreciate its own awesomeness, and understand how bad the movie was.

There are two contenders for Best Line so far:

"I'm too young to die!"

"I'm not, but I don't wanna!"

But I think the clear winner is:

"Don't worry, Sokka. Where we're going, you won't need any pants!"
