Now I See

We met the boy's kindergarten teacher last night.
"Oh, hi, it's so nice to meet you! The TA and I just love what you put in his lunches every day. We think it's hilarious."
"Huh? Oh, uh, yeah, ha ha."

Later, discretely to the wife: "What do we put in his lunches every day?"
"Raw spinach and whole wheat cous cous. Why?"
