This was one popular chinese joke I come across. There was a man whose nickname is “None of my business”. One day while he was walking back from the market, a passer-by came to ask him a question: “Will you mind another’s business?” He asked. “None of my business” replied: “ No, no, none of my business.”

The passer-by asked again: “ Will you do it if it benefits the party?” And he replied again: “ No, no absolutely none of my business!”

As they continued walking, “ None of my business” felt that the sack of rice he’s carrying is getting lighter and when he realised that most of the grains of rice were spilled out from the sack, he said to the passer-by: “ Why didn’t you tell me earlier?” The passer-by replied: “ No, no, absolutely none of my business!”
