Did you hear the one about...

A Tibetan, a Chinese and a Japanese were all travelling together on a small aircraft from Lhasa to Shigatse.

The Japanese took out his camera and threw it out of the window of the plane. Startled, the Chinese asked him why he had done this.

"We have plenty of those where I come from, I don't need it" replied the Japanese.

The Chinese took out his radio and threw it out of the window. “Why did you do that?" asked the Tibetan.

"We have plenty of those where I come from" replied the Chinese. "I don't need it" he added.

The Tibetan thought for a moment. He had nothing to throw out of the window. Without warning he grabbed the Chinese by the throat and threw him out of the window.

Alarmed, the Japanese asked him why he had done such a thing. "We have plenty of them where I come from, I don't need it!" was the reply.
