I've been thinking about this one shot for quite some time, especially after learning JK Simmons is voicing Tenzin in the new series, so thoughts of Cave Johnson from Portal 2 entered my mind. I like to call Tenzin, CEO of Airbending Science!

One day Avatar Aang, his wife Katara and their 17 year old son Tenzin – were enjoying a nice peaceful day at home. Avatar Aang made special Air Nomad pies with the help of his lovely wife, Lady Katara.

The 17 year old Airbender spoke "Hey, mom and dad! What are you guys making?"

"We're making some Air Nomad pies, you haven't lived until you've tried them!" Aang emphatically said, Tenzin's face lit up with a smile.

"Hey, we have one pie, don't we, Aang?" Katara said.

"Yes, yes we do!"

Katara went to the window and grabbed the one pie, it was ready be eaten.

"Here it is, Tenzin. A lemon pie!"

"What did you say?" Tenzin said astonished.

"Uh, it's a lemon pie, son!" Katara said.

"Alright, I've been thinking about this. When life gives you lemons, don't make lemon pies." Tenzin said.

"Yeah!" Korra said from the spirit world

Tenzin continued "Make life take the lemons back!"

Katara and Aang just looked at each other, confused at what their son was saying to them "Get mad!"

"Yeah!" spirit Korra said again.

"I don't want your damn lemons, what am I supposed to do with these?"

"Yeah, take the lemons!" Korra said.

"Tenzin…" Katara said.

Tenzin continued his rant on lemons "Demand to see life's sifu!"

Spirit Korra answered again "Yeah!"

"Make life rue the day it thought it could give Tenzin lemons!"

"Son…" Aang said, with Katara and himself at a loss for words with Tenzin's rant.

Tenzin got up from his seat at the table "Do you know who I am? I'm going to be the man that airbends your house down! With the lemons!"

"Oh, I like this guy!" spirit Korra spoke again.

Katara had a lot of worry on her face "Please, calm down Tenzin!" Katara said.

It was at this day, that Katara or Aang never mentioned lemons or pies again. Or Tenzin would airbend life's sifu house. Unfortunately, Aang couldn't find life's sifu in the spirit world to let him know.
