An odd coincidence?

I have a theory. (No, it’s not bunnies.) One of my favourite foods is soy beans. I love it both because they’re tasty, and because they’re so changeable. I mean, what other substance can be used to make a hard white solid (tofu), and a viscous black liquid (soy sauce)? Hey, waitaminnute. “Soy beans” are oil! It’s all just different names for petrochemicals!
