"Apparently, one in five people in the world are Chinese. And there are five people in my family, so it must be one of them. It's either my mum or my dad. Or my older brother, Colin. Or my younger brother, Ho-Chan-Chu. But I think it's Colin"

This quote by Tim Vine is a humorous take on the fact that a person in 5 people on the planet are Chinese. He is implying that a person of the five individuals in his family need to be Chinese, and he is trying to figure out which one it is. He starts by listing the possible prospects: his mother, daddy, older sibling Colin, and younger brother Ho-Chan-Chu. He then concludes that it must be Colin, as if it were that basic to determine who is Chinese. This quote is a lighthearted method of poking fun at the fact, and it is a funny method of explaining the absurdity of attempting to think someone's ethnic background based upon a fact. It is also a tip that we need to not make assumptions about someone's background based upon a statistic.
