Zuko is Leavin
This video was recently posted on devart, with a link to youtube where you can get sound. OMG go watch it. It is made of so much hilariousness. Zuko singing a pop song. It's magical.
I didn't make the video (I'm no where near awesome enough), so please go comment here and let it be known how awesome it is. (someone else apparently posted it for the person, though, since the person that made it is sick ): )
