"My, what black teeth you have!"

I was digging around in passport documents and the like one day, and I came across a cookie tin with some old photos. One picture was of us and some older Chinese guests from about 20 years ago. When I showed the picture to my father, he recounted their visit.

Apparently, I pointed out, "Daddy, his teeth are really black."

Dad tried to brush me off, but I was intent on telling him. By the time he managed to shush me up, our guest's face was already flushed with embarrassment.
