Don't Eat Yellow Snow

Woudl you believe that to some, this is actually valuable advice and not just a goofy/sarcastic life tip? I won't mention any names, but there was someone I jokingly said this to yesterday, someone who very much likes to eat snow. For many minutes after a tiny little voice called out, "Mommy, there's yellow snow!" Well, don't eat it! At least this unnamed person doesn't run with scissors.
