In one hospital, over a period of 14 hours, 19 boys — and no girls — were born.

It's in the news as if it's amazing, but of course it's no more unusual than any other combination of boys and girls born anywhere else over any other period you might define. In fact, it's less unusual, since the choice to define the relevant period and end it when the last boy was born maximized the presence of boys in the group.
