So I went to the Philadelphia Art Museum (which is no longer on strike. yay) with a few friends. We saw a cricket cage for cricket fighting, which apparently is a thing. But only for male crickets, which begs the question: how does one tell boy cricks from girls?

Chasing this thread I learned about the Zen-Nippon Chick sexing method, practitioners of which are well paid in the chicken farming world. 

Anyway, go to museums folks. It expands the mind.
