Quote from Beverly in You Got Zuko'd
Beverly: You think this is just about cooking? There is so much more that goes into taking care of our Barry. Lainey: Like what? Beverly: Washing his Flyers shirts, flipping his covers when he sweats at night, reminding him to make when he waits too long and gets plugged up. Lainey: What is that? What are you doing? Beverly: It's the signal for poo-poos. You gotta learn the signal. Lainey: I don't wanna learn the signal! Barry: Don't make her do the signal, Mom! Beverly: She has to learn the signal! Lainey: I don't wanna learn the signal. Beverly: Now, this hand is the potty, beckoning the poo-poos, and in they go. Huh? She's not doing it! Lainey: Of course I'm not doing it!
