(The doorbell rings)
Grandma: Stanley, answer the doorbell.
Grandpa: Who you calling a dumbbell?
Julie: Grandpa, she said "doorbell."
Grandma: Must be my friend, Sophie.
Grandpa: If it is, she needs a shave.
Carl: Pop, it's me, Carl.
Grandpa: It's the incredible hulk.
(Carl comes in, and the dialog continues)
Grandpa: She doesn't want to talk to you, and neither do I.
(Grandma comes into the room)
Grandma: Oh, it's you. I'm not talking to you.
Grandpa: Three strikes, you're out.
Carl: Anybody who can't obey my rules, can't live in my house. It's time you all learned that I am the boss here. The master, the chairman of the board, the commander in chief. (Nell gets up) Where are you going?
Nell: I'm going to fill the bathtub with some water, so you can walk on it.
