Epiphany

BEN (holding up a piece of chicken): Does chicken come from an animal?

ME: It's a chicken.

BEN: No, I don't mean what is it, I mean what animal is it!

ME: It's a chicken. (In response to his blank stare I elaborate with some chicken noises).

BEN: OOOOHHHHHHH!! So THAT'S why they call it chicken!
