I once had the interesting experience of singing "Mr. Wu" with a jazz band (me on tenor banjo) - many, many years ago. I couldn't understand why the rest of the band were looking at me and pissing themselves laughing.

When I put my specs on, I saw - to my total embarrassment - half a dozen Chinese people in the front row... To their credit, one of them came up to me afterwards and said how much he and his friends had enjoyed the band.

I still felt like a tit.
