The Last airbander

One thing I really want to see is a flashback of Aang giving Tenzin advice on how to pick up the ladies.

Aang: "So son, I see you've been spending a lot of time with that Pema girl..."

Tenzin: "Yeah, she's nice..."

Aang: "I think it's time I teach you the ways to a woman's heart Tenzin."

Tenzin: "Dad, I don't..."

Aang: "I have years of experience in this field son, trust me."

Tenzin: "Dad, it's not that I don't trust you, it's just that I don't really want to.."

Aang: "IF YOU WANT TO BE A MASTER AIRBENDER YOU HAVE TO MASTER HOW TO BE A GENTLEMAN. NOW LET ME TEACH YOU."

Tenzin: "... fine."

Aang: "Okay, now to break the ice, ask her out to go penguin sledding."

Tenzin: "There's no penguins in Republic City, Dad."

Aang: "Okay then. Next, remember that marble trick I taught you a few days ago?"

Tenzin: "Well yes, but I fail to see how that's relevant to the-"

Aang: "Show it to her."

Tenzin: "But Dad-"

Aang: "Show her!"

Tenzin: "That trick is so boring-"

Aang: "Show her the trick Tenzin, trust me."

Tenzin: "It has no technical merit at all-"

Aang: "TENZIN SHOW PEMA YOUR MARBLES!"

Tenzin: "Dad that sounds-"

Aang: "I HAVE YEARS OF EXPERIENCE AND I'M THE AVATAR. TRUST ME I KNOW WHAT I'M DOING."
