Interesting question… the following is extracted from a media article published here in Singapore:
”He's Teochew but speaks Hokkien more fluently. I ask him about rumours that his father was the late comedian Wang Sa of Ah Pui-Ah San fame. He smiles and says: "I'm very amused by that. Many people have asked me."
So is it true? "If they associate me with having some good humour, I don't mind. I'll take it with some good humour," is all he will say.“
