Old k joke

There are three little pigs. Who is pig A, where is pig B and what is pig C? One day, pig A and pig Li Li were at the door, and pig C was on the roof. A wolf found them and wanted to eat them, so he rushed to pig A. ...

Wolf: Who are you?

Pig A: Yes!

Wolf: What?

Pig A: What's on the roof?

Wolf: I mean what's your name?

Pig A: My name is "Who" and "What" is on the roof.

The wolf asked pig B again.

Wolf: Who are you?

Pig B: I'm not "who", but "who" (pointing to pig A)

Wolf: You know what?

Pig B: Hmm.

Wolf: Who is it?

Pig B: Yes.

Wolf: What?

Pig B: What's on the roof?

Wolf: Where?

Pig B: "Where" is me.

Wolf: Who?

Pig b: who is it (pointing to pig a again)

Wolf: How should I know?

Pig B: Who are you looking for?

Wolf: What?

Pig B: On the roof.

Wolf: Where?

Pig B: It's me.

Wolf: Who?

Pig B: I'm not who, I'm who.

Wolf: Good heavens!

Pig A Pig B: "My God" is our father.

Wolf: What, it's your father?

Pig B: No!

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

Pig A, B and C: Do you know our grandfather?

Wolf: What?

Pig A: No, "Why" is our grandfather.

Wolf: Why?

Pig A: Yes!

Wolf: What's this?

Pig A: No, it's why.

Wolf: Who?

Pig A: Who am I?

Wolf: Who are you?

Pig A: Yes, I am "Who".
