Who knows the story about the names of the three sheep?

One day, a wolf eats three piglets,

2 at the door and one on the roof.

Wolf: Who are you?

Pig A: You are right!

Wolf: What?

Pig A: "What" is on the roof!

Wolf : I mean "What's your name?"

A: "Who" am I, what's on the roof!

The wolf couldn't get the answer, so he asked Pig B,

Wolf: Who are you?

B: I am not who, who is he?

Wolf: Do you know him?

B: Yes!

Wolf: Who is he?

B: Yes!

Wolf: What?

B: What’s on the roof!

Wolf: That’s my father.

A, B: That’s my dad

Wolf: What is your father?

B: No, he is on the roof!
