So he asked the seller: Why is your parrot so cheap?
Vendor: My parrot is stupid! Shit, I've been teaching for a long time. All I can say at present is one sentence-"Who is it?"
Xiao X thought it was cheap anyway, so he bought it.
When he got home at night, he thought, "I don't believe in teaching, and I don't believe in teaching!" " "So little X taught it to say something else all night.
But in the morning, the parrot still just said, "Who is it?" So little X got angry, locked the door and went to work.
After a while, a gas collector (Z for short) came.
Little Z, "Knock, knock ..." (knocking at the door)
Parrot: Who is it?
Little z: gas inspector.
Parrot: Who is it?
Little z: gas inspector.
Parrot: Who is it?
Little z: gas inspector.
In the evening, little X came back. I saw a man lying on the ground in front of my house, foaming at the mouth.
Little x: yo ~! Who is this?
I heard it in my room: the gas inspector.
