Annoying statisticians (for a worthy cause)
Nonbinary and intersex stuff isn't really my bailiwick, as I am neither. I'm always in favor of annoying statisticians, though.
Favorite factoid regarding people getting creative with the census: as I recall, in the 2000 US census, several hundred people claimed to use the "subway" in Cincinnati, despite the fact that Cincinnati has no subway.
What did those poor, innocent statisticians ever do to you?
