Master Pakku was sleeping.

Aang was not.

Creeping into the waterbending master's room, Aang could only think of one thing.

"Penis penis penis penis penis penis penis penis."

Making sure to be as quiet as possible, he slowly pulled down Pakku's bedcovers, leaving the nude man sleeping quietly on his bed.

Aang lowered his face to the older man's crotch...

...and bit his penis off.

The end.
