What is the word used in the joke that ipartment Lv Ziqiao asked Ceng Xiaoxian to tell?

There is a beautiful small village.

One day,

A Lama came from the south,

With five catties of Ma Kun in his hand.

A mute comes from the north,

You have a trumpet in your waist.

The monks in the south of Amazon want to exchange Amazon for the mute in the north.

Dumb people don't want to trade horns for Lama's horse,

The Lama must change the horn of the dumb horn.

The Lama pointed a gun at another speaker and slapped the mute.

The mute took off his horn and gave it to the Lama who was in Lamason.

I don't know if it was the Lama of Lamason who struck the other horn dumb.

Don't honk the horn. The mute honked his horn at the Lama pulling the horse.

Lama stewed flounder,

Dumb, beep, beep, beep, blow the horn.
