Ban Hammer III
It hurt the most to ban his uncle, but after a concerted effort between Iroh and Katara to impose a feeding and break schedule on him, he banned them both and posted armed guards in front of the door. When Iroh sweet-talked the female guards into letting him in, Zuko's pain instantly disappeared, and he switched the women out for male guards, and banned Iroh from the entire hallway. Iroh considered it a game, and used the guards at the end of the hallway as messengers, annoying Zuko until he could take no more. As usual, Iroh won. Zuko ate.
I like this Ban Hammer series. So far, this one's got to be my favorite. Iroh's awesome like that.
