 In New York City, there are two non-bald people who have the same number of hairs on their head.

The human head can contain up to several hundred thousand hairs, with a maximum of about 500,000. In comparison there are millions of people in New York City. According to pigeonhole principle, at least two of them must share the same number of hairs.
