A popular joke is that whenever Apple launches a product, customers have to sell their kidney just to be able to afford it.

A man carrying a sign with "selling kidney" written on it climbed on top of a seven-meter-tall tree in front of a hospital in Beijing, according to dfic.cn on Friday.

He claimed that he went to the hospital and told them that he wanted to sell his kidney but no one paid him attention. That's why he climbed on top of the tree to get noticed. The rescuers tried to persuade him for three hours to climb down but failed. They finally dragged him by a crane to a safe place.

He didn't utter a word about kidney while being lifted to a safe place.

The rescuers force him off the tree to the platform of the crane after three hours of unsuccessful persuasion. [Photo/IC]
