What's so funny?

One day, the wolf wanted to eat three little pigs. Two of the three little pigs are at the door and one is on the roof. Pig 1 and pig 2 are at the door, and pig 3 is on the roof. The name of the pig 1 is "Who".

,

Pig 2' s name is "Where"

,

Pig 3' s name is "What". So there was a wonderful dialogue.

(Wolf): Who are you?

(Pig 1): Right.

(Wolf): What?

(Pig) 1: What's on the roof?

Wolf: I mean, what's your name?

(Pig 1): My name is "Who" and "What" is on the roof!

(Wolf asks Pig 2 again): Who are you?

Pig 2: I'm not a "who", he is a "who". Pointing at the pig 1

(Wolf): You know him?

(Pig 2): Hmm!

Who is he?

(Pig 2): Yes.

(Wolf): What?

Pig 2: What is on the roof!

(Wolf): Where?

(Pig 2): "Where" is me.

Who?

(Pig 2): Who is he? Pointing at the pig 1 again.

(Wolf): How should I know?

Pig 2: Who are you looking for?

(Wolf): What?

Pig 2: He's on the roof?

(Wolf): Where?

(Pig 2): It's me.

Who?

Pig 2: I'm not a "who", he is a "who".

(Wolf): Good heavens!

(Pig 1.2): "My God" is our father.

(Wolf): What does your father do?

(Pig 2): No!

The wolf couldn't stand it anymore and sighed: Why?

(Pig 1.2.3): Do you know our grandfather?

(Wolf): What?

(Pig 1): No, our grandfather is "Why".

(Wolf): Why?

(Pig 1): Right!

(Wolf): What is it?

(Pig 1): There is no "why".

Who?

(Pig 1): Who am I?

(Wolf): Who are you?

(Pig 1): Yes, who am I?

(Wolf): What?

Pig 1.2): "What" is on the roof. ~ ~ ~ ~ The wolf shouted, Oh, my God!

I'm crazy!

So he jumped into the pot and cried, three pig brothers. Eat me, I have no attachment to life!
